Question

Which of the following is not a function of proteins?

Medium
A. Formation of hair, wool, skin and nails
B. As a biological catalyst in the form of enzymes
C. As food in the form of meat, eggs
D. As energy provider for metabolsim

Answer 1

Proteins are not primarily used by the body as an energy provider for metabolism but have key roles in structure, enzyme activity, molecule transport, and nutrition.

Step-by-step explanation:

The question you're asking is about the functions of proteins, more specifically which of the options given is not a primary function of proteins. The correct answer to the question is that proteins are not primarily used by the body as an energy provider for metabolism. This role is typically taken by carbohydrates and fats, with proteins being used mainly in cases of energy deficit.

While proteins can be converted into glucose or triglycerides and used for energy, their main functions include:

• Forming structural components such as hair, skin, and nails, and providing support and protection to various tissues.
• Acting as biological catalysts in the form of enzymes, such as trypsin, to accelerate biochemical reactions.
• Transporting molecules and ions in the body, like hemoglobin which carries oxygen.
• Being a source of nutrients when consumed in dietary forms such as meat and eggs.
