which of the following is not a function of proteins in the body?
select one
a. providing fuel for energy needs
b. facilitating chemical reactions
c. maintaining volume of body fluids
d. protecting the body against diseases
e. inhibiting the absorption of cholesterol

Explanation:

To determine the non - function of proteins, we analyze each option:

• Option A: Proteins can be broken down to provide energy (fuel) when needed, so this is a function.
• Option B: Enzymes (which are proteins) facilitate chemical reactions, so this is a function.
• Option C: Proteins like albumin help maintain the volume of body fluids, so this is a function.
• Option D: Antibodies (proteins) protect the body against diseases, so this is a function.
• Option E: Inhibiting cholesterol absorption is mainly the role of substances like plant sterols or certain drugs, not a function of proteins.

Answer:

E. Inhibiting the absorption of cholesterol
