Question

what are some examples of functions of proteins? (0:50 - 1:10)
a. enzymes (to start and speed up reactions)
b. structure and support (framework and shape of cells and tissues)
c. deliver energy to cells
d. movement of structures like muscles
e. defense- antibodies are made of protein and defend the body against invaders like viruses
f. store genetic information

Explanation:

• Enzymes: Proteins act as enzymes to catalyze (start and speed up) biochemical reactions.
• Structure and support: Proteins like collagen provide structural support to cells and tissues, giving them shape and framework.
• Movement: Proteins (e.g., actin and myosin in muscles) are involved in muscle movement.
• Defense: Antibodies (proteins) defend the body against pathogens (e.g., viruses).

Energy delivery to cells is mainly by carbohydrates and lipids. Storing genetic information is a function of nucleic acids (DNA and RNA).

Answer:

A. enzymes (to start and speed up reactions), B. Structure and support (framework and shape of cells and tissues), D. Movement of structures like muscles, E. Defense - antibodies are made of protein and defend the body against invaders like viruses.
