All of the following statements about enzymes are true, except: a. they increase the rate of a reaction. b. they function in an aqueous environment. c. a single enzyme typically reacts with many different substrates. d. they lower the activation energy of a reaction.

c. A single enzyme typically reacts with many different substrates.

Explanation:

Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.

Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
