NEET BIOLOGY

Detailed explanation-1: -Dietary carbohydrates provide glucose that body cells can use for energy. Excess glucose beyond what the body needs for immediate energy is converted into glycogen, a storage form of carbohydrate, or converted into fat and stored in body fat cells. Glucose provides energy for all body cells.

Detailed explanation-2: -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-3: -The primary function of carbohydrates is for short-term energy storage (sugars are for Energy). A secondary function is intermediate-term energy storage (as in starch for plants and glycogen for animals).
