Understanding Enzyme Function

Very Easy Biochemistry Enzymes

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They do this by lowering the activation energy required for a reaction to occur. Without enzymes, many biochemical reactions would proceed too slowly to sustain life.

Which of the following statements about enzymes is true?

Enzymes are consumed in the reactions they catalyze.

Enzymes increase the activation energy of a reaction.

Enzymes can be reused multiple times after catalyzing a reaction.
