Question

Select the correct answer.

Question 1: The number of molecules with which an enzyme reacts is the

a) end product.

b) optimum.

c) substrate.

d) turnover number.

Answer 1

The number of molecules an enzyme reacts or catalyzes per second is called as TURN OVER NUMBER.

Hence, the answer is option d. TURNOVER NUMBER

End product is the molecule produced from substrate molecules when enzyme catalyzes it. Hence, option a is not correct.

Optimum conditions represent the optimal temperature and optimal pH where the enzyme catalyzed rate of reaction is at its maximum. Hence, option b is not correct

Substrate is the molecule which is altered by enzyme and results in the formation of product. Hence, option d is also not correct answer.
