Question

Quizplus · Accepted Answer

A catalyst is a substance that speeds up a chemical reaction, but it remains unchanged and unaffected by the reaction. It helps to lower the activation energy required for the reaction to proceed, without being consumed or altered in the process. Hormones, amino acids, and proteins do not necessarily speed up chemical reactions, and they may also be consumed or altered during chemical processes.
