Question

which of the following is a function of proteins in cells? options: hormone production, energy storage, genetic information storage, enzyme activity. (additional context: biomolecules (updated 2023), hormones, speech bubble: \glucose, this way. keep moving, please.\)

Explanation:

To determine the function of proteins in cells, we analyze each option:

• Hormone production: Hormones can be proteins (e.g., insulin), but this is a specific role, not the primary general function of most proteins.
• Energy storage: Carbohydrates (like glycogen) and lipids are the main energy storage molecules, not proteins.
• Genetic information storage: DNA and RNA store genetic information, not proteins.
• Enzyme activity: Many proteins act as enzymes, which are biological catalysts that speed up chemical reactions in cells. This is a fundamental and widespread function of proteins.

Answer:

Enzyme activity
