Which statement is true of proteins

1 answer

Proteins are large, complex molecules that play many critical roles in the body. Here are some true statements about proteins:

  1. Made of Amino Acids: Proteins are composed of long chains of amino acids, which are linked together by peptide bonds.

  2. Structure and Function: The specific sequence of amino acids determines the protein's structure and ultimately its function in biological processes.

  3. Enzymatic Role: Many proteins function as enzymes, catalyzing biochemical reactions that are essential for life.

  4. Transport and Storage: Certain proteins are involved in the transport and storage of molecules, such as hemoglobin, which carries oxygen in the blood.

  5. Immune Response: Proteins such as antibodies play a key role in the immune system, helping to identify and neutralize foreign objects like bacteria and viruses.

  6. Structural Components: Proteins provide structural support in cells and tissues, such as collagen in connective tissues and keratin in hair and nails.

  7. Energy Source: While not the primary function, proteins can serve as an energy source if carbohydrates and fats are not available.
