Question

which of the following is a function of proteins in cells? 7/10 options: enzyme activity, hormone production, genetic information storage, energy storage

Explanation:

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

• Energy storage: Typically done by carbohydrates (e.g., glycogen) and lipids, not proteins.
• Genetic information storage: DNA and RNA are responsible for storing genetic information, not proteins.
• Hormone production: While some hormones are proteins (e.g., insulin), hormone production is not a primary or defining function of all proteins in cells.
• Enzyme activity: Many proteins function as enzymes, which are biological catalysts that speed up chemical reactions in cells. This is a well - known and major function of proteins.

Answer:

Enzyme activity (the option with the label "Enzyme activity" corresponding to the green bar in the provided options)
