Question

What role do enzymes play in cellular respiration?

A. Enzymes enable reactions to proceed slowly at low temperatures.
B.Enzymes enable reactions to proceed quickly at high temperatures.
C.Enzymes allow reactions to take place at normal body temperature.

Answer 1

the answer is c because neither too low or hogh temperature will enzyme work
ie low temp cause enzyme to be inactive
high temp cause enzyme to be denatured

Answer 2

Answer: Option C

Step-by-step explanation:

Enzymes acts as catalyst for the reaction and decrease the energy required for the reaction to take place. The threshold energy can be defined as the minimum energy required to start a reaction.

Enzymes slow down this energy at the normal body temperature. The optimum temperature for the working of enzymes is 37 degree Celsius and at pH 7.

The enzymes allows the reaction to take place at the normal body temperature lowering the threshold energy.
