What are the factors which influence enzyme activity? Discuss them in brief.

Options

A. pH
B. concentration, substrate, cofactors
C. enzyme poisons
D. all of the above.

Answer

D

Explanation

Enzymes are influenced by temperature
1. inactivated usually above `60^@`C
2. rate of reaction is controlled as in any chemical reaction , the rate is approximately doubled by each `10^@C` increase
3.low temperature slow the reactions PH.There is an optimum pH for every reaction poisons some enzymes themselves can be harmful to the organism but they are also susceptible to compounds like cyanide , etc. , which inativate them concentration the rate of a reaction is directly proportional to the amount of enzyme present in relation to substrate . If a coenzyme or specific activator is required that substances may control the overall rate of the reaction also.
