Which of the following is false about enzymes?
a. they lower the activation energy of biological reactions.
b. they increase the temperature of biological reactions to speed them up.
c. they are highly specific in their catalytic activity.
d. they act as biological catalysts. none of the above

B

Explanation:

Enzymes do not increase the temperature of biological reactions themselves.

Increase in temperature of the medium is needed to speed up enzymatic activity but only to a specific point.

Enzymes require an optimum temperature which is the maximum amount of temperature needed to convert substrate to product per unit time.
