Answer :
Option (3) is correct. Carbohydrates serve as a preferred and quick source of energy.
At every stage of life, carbohydrates, commonly referred to as carbs, are essential. They are the main energy source for the body and the preferred energy source for the brain. The body converts carbohydrates into glucose, a form of sugar. Your body's cells, tissues, and organs use glucose as fuel.
They function as energy producers, energy stores, macromolecule builders, protein scavengers, and supporters of lipid metabolism. As a metabolic fuel, carbohydrate has two key benefits over fat: it is the only fuel that can produce ATP in the absence of oxygen, and when glucose is oxidized, more ATP is produced per O2 used than when fat is oxidized.
