Answer:
c. Pyridostigmine binds to the acetylcholinesterase active site and prevents sarin from binding to and modifying the enzyme active site.
Explanation:
Sarin is a toxic compound which inhibits acetylcholinesterase enzyme. This enzyme degrades the neurotransmitter acetylcholine after the required muscle cell stimulation. In absence of its activity, acetylcholine is not degraded and the muscle cells are stimulated uncontrollably. The muscles are not able to relax which ultimately proves fatal for the victim.
Pyridostigmine is also an acetylcholinesterase inhibitor like Sarin. However its period of inhibition is short compared to organophosphorus inhibitors like sarin. It competes with sarin and replaces it in the active site of acetylcholinesterase. The enzyme is still inhibited but for a shorter time as compared to inhibition by Sarin. Hence after sometime, it becomes functional again and resumes its normal activity. Acetycholine starts getting degraded relaxing the muscles.
Based on the information in the table,
- the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
- the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.
<h3>What are enzymes?</h3>
Enzymes are organic catalysts that speed up the chemical reactions occurring in the body.
Enzymes are very essential in most metabolic reactions occurring in the body.
The deficiency or inactivity of an enzyme in the body will lead to an accumulation of the substrate on which the enzyme acts on.

in conclusion, enzymes are important for biochemical reactions.
