Question

list the functions of proteins in the text area below.

Explanation:

Proteins have multiple functions. They act as enzymes to catalyze biochemical reactions, are structural components of cells and tissues (like collagen in connective tissues), function in transport (e.g., hemoglobin carrying oxygen), play roles in immune response (antibodies are proteins), and are involved in cell - signaling and regulation of gene expression.

Answer:

• Catalyze biochemical reactions as enzymes.
• Provide structural support in cells and tissues.
• Transport substances (e.g., oxygen by hemoglobin).
• Mediate immune response (antibodies).
• Participate in cell - signaling and gene regulation.
