energy
O
C. Enzymes prevent reactions from occurring.
O
D. Enzymes lower the activation energy required for reactions to

Answer 1

Answer: it,s D

Explanation:

Enzymes are known as biological catalyst and work by lowering the activation energy of a reaction. They do this by providing an alternative pathway which speeds up the reaction without the catalyst undergoing a permanent change. ... An important thing to remember is that enzymes do not affect the equilibrium of a reaction.
