Question

Which statement best describes a relationship between enzymes and a simple biological reaction? A) Enzymes will increase the amount of substrate formed during a biological reaction. B) Enzymes will decrease the amount of substrate formed during a biological reaction. C) A reaction rate can be increased when the specific enzyme for a biological reaction is present. D) A reaction rate can be decreased when multiple enzymes for a biological reaction are present.

Answer 1

The Option C is correct.

• C) A reaction rate can be increased when the specific enzyme for a biological reaction is present.

By increasing the enzyme concentration, the maximum reaction rate greatly increases.

Conclusions:

The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
