Question

section v:

1. proteins are macromolecules created from monomers called
2. list three functions of proteins in living organisms.

Explanation:

For question 34, proteins are made up of amino acids as their monomer units. For question 35, proteins have multiple functions. Enzymes (which are proteins) catalyze biochemical reactions. Structural proteins like collagen provide support in tissues. Antibodies (a type of protein) are crucial for the immune system to recognize and neutralize pathogens.

Answer:

1. amino acids
2. - Catalysis (enzymes catalyze reactions).

• Structural support (e.g., collagen in connective tissues).
• Immune response (antibodies help fight infections).
