Question

Proteins contain both acidic and basic R groups and can, therefore, function as
A) energy storage macromolecules.
B) structural macromolecules.
C) buffers.
D) catalysts.
E) genetic material.

Accepted Answer

Proteins can act as buffers because they contain both acidic and basic R groups, which can accept or donate protons to maintain a stable pH in a solution. While proteins can also function as energy storage molecules, structural molecules, and catalysts, the presence of acidic and basic R groups does not directly contribute to these functions. Proteins are not genetic material.
