HUMAN NUTRITION

Detailed explanation-1: -In cases where carbohydrates have been depleted, the body can utilise protein and fats for energy. Your metabolism is the chemical reactions in the body’s cells that change this food into energy.

Detailed explanation-2: -When there is a lack of glucose, our bodies can use protein or fat for energy. Fats are broken down into fatty acids and ketone bodies. Our brain uses ketone bodies in the absence of glucose. Technically we don’t need carbohydrate for energy but using fats and ketone bodies isn’t our bodies’ preferred source.

Detailed explanation-3: -Insulin helps our bodies store extra glucose Insulin helps our cells convert glucose into energy, and it helps our bodies store extra glucose for use later.

Detailed explanation-4: -The primary source of energy for animals is carbohydrates, mainly glucose. Glucose is called the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules through a series of catabolic chemical reactions.
