Allosteric Regulation in Enzymes: Understanding Compound C Interaction

What does it mean if compound C reacts with the allosteric site of enzyme A?

1. It will exhibit allosteric regulation

2. It will increase enzyme efficiency

3. It will decrease enzyme efficiency

Final answer:

If compound C reacts with the allosteric site of enzyme A, it will exemplify allosteric regulation. Depending on whether compound C is an allosteric inhibitor or an allosteric activator, this could increase or decrease the enzyme's efficiency.

Explanation: If compound C reacts with the allosteric site of enzyme A, it would exemplify allosteric regulation. There are two types of allosteric regulation, namely allosteric activation and allosteric inhibition. In both instances, a molecule binds to the allosteric site of the enzyme that isn't its active site, leading to a change in the enzyme's shape.

If compound C is an allosteric activator, it will induce a change in the enzyme that increases its affinity for its substrate, making the enzyme more efficient. Alternatively, if compound C is an allosteric inhibitor, it will induce a change that decreases the enzyme's affinity for its substrate, making the enzyme less efficient.
