what is the necessary coenzyme for transamination reactions? select one: a. pyridoxal phosphate b. thiamine pyrophosphate c. coenzyme a d. nad
Answers
The necessary coenzyme for transamination reactions is pyridoxal phosphate (option A). Pyridoxal phosphate is a derivative of vitamin B6, which plays a crucial role in the metabolism of amino acids.
It acts as a coenzyme for transaminases, which catalyze the transfer of an amino group from an amino acid to a keto acid, forming a new amino acid and a new keto acid. Pyridoxal phosphate is required for the transamination of most amino acids, including those that are essential for human health. The coenzyme is necessary to stabilize the intermediates formed during the reaction and to facilitate the transfer of the amino group. Without pyridoxal phosphate, transamination reactions cannot occur, leading to a disruption in the metabolism of amino acids. Thiamine pyrophosphate, coenzyme A, and NAD are also important coenzymes in other metabolic reactions, but they are not involved in transamination reactions. In summary, pyridoxal phosphate is the necessary coenzyme for transamination reactions, and its absence can lead to serious metabolic disorders.
Transamination reactions play a crucial role in amino acid metabolism, as they facilitate the transfer of an amino group from one molecule to another. Pyridoxal phosphate, derived from vitamin B6, serves as a vital coenzyme in these reactions, enabling the conversion of amino acids into other essential metabolic intermediates. This process supports the synthesis of non-essential amino acids, as well as the generation of various compounds involved in energy production and other critical cellular functions.

Using evidence from the Sea Star Wasting Disease case study, explain how change in allele frequency over time (evolution) happens due to: (Pick one or two of the following to explain)
1) Species increasing in number
2) Mutation and reproduction results in a variety of genes passed on and carries by individuals of a population
3) Organisms in a community compete for resources
4) Organisms who can survive, thrive, and reproduce will increase in number
Answers
Due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.
Allele and allele frequency An allele is one of an alternate form of a gene.Allele frequency is the percentages of each of the different alleles of a particular gene in a population.Changes in allele frequency that occur over time because of one or more evolutionary factors such as:
genetic drift, gene flow, mutation, non-random mating, selection, etc.The change in allele in the sea star wasting disease was due to genetic drift which are random change in allele frequencies that occurs in small populations occurring due to such factors as disease.
Evidence of allele frequency change in sea star wasting disease1. Mutation and reproduction results in a variety of genes passed on and carries by individuals of a population.
The changes that occcured at gene Locus 1048 and 1166 due to mutation helped the post-SSWD starfish to survive and reproduce giving rise to offspring with those changes.2. Organisms who can survive, thrive, and reproduce will increase in number.
The about 20% post-SSWD starfish that survived due to the change in their allele were able to survive and reproduce rapidly giving rise to offspring such that the individuals in the population have almost risen to pre-SSWD numbers.
Therefore, due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.

The statement that accurately describes plant virus infections, Plant virus infections are caused by the invasion of a virus into the plant cells, where they replicate and spread. b) They can be spread via the plasmodesmata.
Plasmodesmata are channels that connect the cells of a plant, and viruses can spread from one cell to another through these channels. Unlike bacterial infections, which can be controlled by the use of antibiotics, there is no cure for plant virus infections. However, there are some measures that can be taken to reduce the spread of the virus, such as removing infected plants or controlling insect vectors that can transmit the virus. Plant virus infections can have a significant impact on plant growth, depending on the severity of the infection and the type of virus. Some viruses can cause stunted growth, reduced yield, or even death of the plant. Therefore, it is important to accurately identify and manage virus infections to prevent losses in crop production.

Which phrase best completes the sentence? according to the modern synthesis of evolution, __________.
Answers
The current synthesis of evolution states that part of the variation that natural selection operates on is produced by genetics and mutation. Here option C is the correct answer.
The Modern Synthesis of Evolution, also known as the Neo-Darwinian Synthesis, is a scientific theory that combines Charles Darwin's theory of evolution by natural selection with Gregor Mendel's laws of inheritance.
It explains how evolution occurs through the process of natural selection acting on genetic variation within populations. According to this synthesis, genetic variation is generated through mechanisms such as mutation and genetic recombination, and this variation is then acted upon by natural selection, leading to the evolution of species over time.
This theory is widely accepted as the current understanding of evolution and is the basis for much of modern evolutionary biology.

What is the medical significance of the O-linked side chain? c. Diagram (draw) the acid fast cell wall. Explain why an acid fast bacterium is not classified as G+ or G.
Answers
A. Gram-positive cell wall: Gram-positive cell wall is composed of various parts, including:
1. Peptidoglycan: This substance gives the cell wall its main structural rigidity and strength.
2. Polymers known as teichoic acids are encased inside the peptidoglycan layer. They interact with host immunological responses and help maintain cell walls.
3. Teichoic acids that are covalently bound to membrane lipids are known as lipoteichoic acid (LTA). LTA has the potential to promote immunity and contribute to pathogenicity. Additionally, they have the ability to associate with host cells and support bacterial attachment to host tissues.
B. Gram-Negative Cell Wall: Unlike gram-positive bacteria, gram-negative bacteria have a more complex cell wall structure. Contains:
1. Outside the thin peptidoglycan layer is the outer membrane, which is composed of proteins and lipopolysaccharide (LPS).
2. LPS: LPS is the main component of the lipopolysaccharide outer membrane. Lipid A, the polysaccharide core and the side chain of the O-antigen make up its three components. LPS is a strong inducer of inflammatory and immunological responses and is essential in the pathogenesis of Gram-negative bacteria.
3. O-linked side chain: One element of LPS is the side chain of the O-antigen. Different bacterial strains have different polysaccharide chains. It affects bacterial virulence, antigenicity and immune response.
C. Acid-fast Cell Wall: Acid-fast bacteria have a different cell wall structure, such as Mycobacterium tuberculosis. Mycolic acids, long-chain fatty acids, are highly prevalent in their cell walls. Because mycolic acids are present in the cell wall, acid-fast bacteria are resistant to common staining techniques such as the Gram stain. Acid-fast bacteria are not classified as gram-positive or -negative because of their unique cell wall structure and staining properties.

Mitosis is the process of cell division that produces two identical daughter cells from a single parent cell. The process is divided into four main stages: prophase, metaphase, anaphase, and telophase. During each stage, specific events occur that ensure the proper separation of the duplicated chromosomes.
Prophase:
During prophase, the chromatin in the nucleus condenses and becomes visible as distinct chromosomes. The nuclear envelope breaks down, and the spindle apparatus, composed of microtubules, forms between the two centrosomes. The chromosomes begin to move toward the center of the cell, and the microtubules attach to the kinetochores on each chromosome.
Illustration of Prophase:
Link of picture unavailable
Metaphase:
During metaphase, the chromosomes line up along the metaphase plate, an imaginary line that runs through the center of the cell. The spindle fibers pull on the chromosomes to ensure they are lined up correctly. The centrosomes are positioned at opposite poles of the cell.
Illustration of Metaphase:
Link unavailable
Anaphase:
During anaphase, the sister chromatids are separated from each other by the spindle fibers and are pulled toward opposite poles of the cell. The spindle fibers not attached to chromatids elongate and push the poles of the cell apart, causing the cell to become elongated.
Illustration of Anaphase:
Link of picture
Telophase:
During telophase, the nuclear envelope reforms around each set of chromosomes at opposite poles of the cell. The chromosomes begin to uncoil and revert to their less condensed form, and the spindle apparatus is disassembled. The cell begins to prepare for cytokinesis, which is the process of dividing the cell into two daughter cells.
Illustration of Telophase:

Overall, these four stages ensure that the genetic material is distributed equally between the two daughter cells.

The pancreas secretes hormones that regulate metabolism of carbohydrates, proteins, and fats.
The hormones insulin and glucagon are secreted by the pancreas and help regulate blood sugar levels and appetite, stimulate stomach acids, and tell your stomach when to empty.
Insulin and glucagon are two hormones secreted by the pancreas that are essential to regulating metabolism. Insulin helps the body absorb glucose from the bloodstream, while glucagon helps regulate glucose levels in the body. Insulin helps cells take in glucose, which is then converted into energy for the body. Glucagon helps the body break down stored energy, such as fat and glycogen, when glucose levels are low.

D) A thermostat switching on an air conditioner when the temperature gets too hot
Explanation:
All other answers choices are negative feedback.
hope this helped!
A thermostat switching on an air conditioner when the temperature gets too hot is an example of positive feedback. Option D is correct.
Positive feedback is a process in which a change in a system causes further changes in the same direction, leading to an ever-increasing effect. In the case of a thermostat, the increase in temperature causes the thermostat to switch on the air conditioner, which cools down the room. This cooling down causes the thermostat to switch off the air conditioner, which then allows the temperature to rise again. This cycle continues until the temperature reaches a desired level.
In negative feedback, a change in a system causes other changes in the opposite direction, leading to a return to the original state. For example, when a herd of buffalo runs away after one of them spots a lion, the other buffalo will also run away, which will reduce the number of buffalo in the herd that are in danger. This will eventually lead to the herd returning to its original state. Option D is correct.
