Question

which statements describe the characteristics of an individual enzyme?
it is specific to one biochemical reaction.
it increases the activation energy needed for a reaction.
it can catalyze many different reactions.
it increases the rate of a biochemical reaction.
it slows down the rate of a biochemical reaction.

Explanation:

Enzymes are highly specific to one biochemical reaction (lock - and - key or induced - fit model). They lower the activation energy (not increase) and increase the rate of a biochemical reaction (catalysts speed up reactions). They are not general catalysts for many different reactions.

Answer:

It is specific to one biochemical reaction.
It increases the rate of a biochemical reaction.
