Which factor is responsible for the inhibition of the enzymatic process during feedback?
Correct answer: C. End product
- A. Substrate
- B. Enzymes
- C. End product
- D. Temperature
Explanation
The correct answer is the end product, as it plays a key role in feedback inhibition by binding to an allosteric site on an enzyme, causing a conformational change that reduces the enzyme's activity. This prevents excessive accumulation of the end product by slowing the metabolic pathway. Substrate, enzymes, and temperature do not directly influence feedback inhibition: substrate concentration affects reaction rates but not regulatory feedback; enzymes are not the regulators but the targets of inhibition; and temperature affects reaction kinetics but is not a mechanism of feedback control.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.

At equilibrium, a scientist added more substrate and observed an increase in the rate of the reaction, which soon declined. He added some more substrate, but this time the rate of the reaction remained unaffected. What was the reason?
