Question

which three are important roles of proteins? select all correct options store genetic codes for traits make up cell membranes control chemical reactions as enzymes structural (muscles, hair, skin, bones) work in the immune system

Explanation:

Proteins are essential biomolecules. They function as enzymes to control chemical reactions. They also contribute to the structure of muscles, hair, skin, and bones. Additionally, they play a role in the immune - system. Genetic codes are stored in DNA, not proteins. Phospholipids make up cell membranes mainly, not proteins as the primary component.

Answer:

C. Control chemical reactions as enzymes
D. Structural (muscles, hair, skin, bones)
E. Work in the immune system
