Question

multiple choice question
what is the major function of carbohydrates in the body?

cellular fuel
catalysts
membrane transport
structural components

Explanation:

Carbohydrates are primarily used as a source of energy (cellular fuel) for the body. Catalysts are enzymes (proteins), membrane transport is done by proteins/channel proteins, and while some carbs have structural roles (like cellulose in plants, but in human body, structural carbs are less major), the main function is energy (cellular fuel).

Answer:

A. Cellular fuel
