AA reaction product regulating its own production
BA substrate speeding up its own consumption
CAn enzyme destroying its own active site
DA cofactor replacing a missing coenzyme
Answer & Solution
Correct answer: A. A reaction product regulating its own production
1. Perhaps the most relevant sources of enzyme regulatory molecules are the products of the cell's own metabolic reactions.
2. Feedback inhibition involves the use of a reaction product to regulate its own further production.
3. The cell responds to an abundance of specific products by slowing down production during anabolic or catabolic reactions.
4. Such products may inhibit the very enzymes that catalyzed their production.
