Answer 1

An enzyme is a catalyst for a chemical reaction that speeds up the rate of the reaction by lowering activation energy.

Step-by-step explanation:

An enzyme can be described as a catalyst for a chemical reaction. It is a protein that speeds up the rate of a specific chemical reaction by lowering the activation energy required. Enzymes do not undergo permanent changes during the reaction and can be reused. For example, the enzyme amylase helps break down starch into sugar molecules.
