LIFE SCIENCE

Detailed explanation-1: -Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

Detailed explanation-2: -Simple carbohydrates are digested quickly and send immediate bursts of glucose (energy) into the blood stream. That’s why you may feel a rush of energy when you eat a dessert, only to be followed by a crash of fatigue when that sudden burst of energy is depleted.
