Answer:

The question lacks options, the options are:

a. They must be continuously replaced after each catalyzed reaction

b. They increase the energy that is released by reactions

c. They are not used up by reactions

d. They increase the energy that must be absorbed by reactions

The answer is C

Explanation:

Enzymes are proteinous biomolecules produced by living organisms. They act as biological catalysts and regulate the rate of biochemical reactions in living cells by binding to the reactants/substrates involved in the reaction. Most reactions will not occur or occur slowly without certain enzymes.

Enzymes, like other catalysts share the same catalytic properties including the fact that they do not get used up or changed in any reaction they regulate, instead they are released and used again.
