Answer 1

Enzymes are proteins that speed up chemical reactions in cells by reducing activation energy.

Step-by-step explanation:

Enzymes are defined as proteins involved in the metabolic processes that break down biological macromolecules. They act as catalysts, speeding up chemical reactions by reducing the activation energy required for the reaction to occur. This allows reactions to occur at a faster rate, enabling cells to carry out essential processes more efficiently.
