Which factor is responsible for inhibition of enzymatic process during feedback?
- Substrate
- Enzymes
- End product
- Temperature
Answer
(3) End product
Solution
In feedback inhibition, the end product of a metabolic pathway inhibits an enzyme acting at an early step of the same pathway.
⇒ When the end product accumulates, it binds to the enzyme (usually an allosteric enzyme) and slows down its own synthesis.
∴ The end product is responsible for feedback inhibition.
