Question

which of the following correctly lists functions of proteins? transporting substances, creating proteins, and fighting disease being the blueprints for life and the bases of heredity providing structure, regulating cell processes, and creating movement sending messages, providing structure, and creating proteins

Explanation:

Proteins have multiple functions. They can provide structural support (like collagen in connective tissues). Enzymes (a type of protein) regulate cell processes by catalyzing biochemical reactions. Motor proteins (e.g., myosin) are involved in creating movement (such as muscle contraction).

• The first option: Proteins can transport substances (e.g., hemoglobin transports oxygen) and fight disease (antibodies are proteins), but they don't "create proteins" in the sense described here. DNA is involved in protein - coding.
• The second option: DNA is the blueprint for life and the basis of heredity, not proteins.
• The fourth option: Proteins can send messages (e.g., some hormones are proteins) and provide structure, but again, they don't "create proteins" in this context.

Answer:

providing structure, regulating cell processes, and creating movement
