Question

which best describes the role of enzymes in a chemical reaction? 29 regulate product reactivity absorb excess energy release unused energy increase the reaction rate

Explanation:

Enzymes are biological catalysts. Catalysts lower the activation - energy of a reaction, which in turn increases the rate at which the reaction occurs. They do not regulate product reactivity, absorb excess energy, or release unused energy in the context of their primary function.

Answer:

increase the reaction rate
