What are the food molecules absorbed by body used for?

The food molecules absorbed by the body are used for a variety of purposes, including:

1. Energy: Carbohydrates, proteins, and fats are all broken down into glucose, which is the body's primary source of energy. Glucose is used by cells for fuel to perform various functions such as muscle contraction and nerve transmission.

2. Building and repair: Proteins are used to build and repair tissues, including muscle, skin, bone, and cartilage. They are also essential for the production of enzymes, hormones, and other molecules needed for body function.

3. Storage: Fats are stored in adipose tissue as a reserve energy source. They can be broken down into fatty acids and released into the bloodstream when the body needs energy.

4. Regulation: Vitamins and minerals play a crucial role in regulating various body processes, such as metabolism, immune function, and fluid balance. They also act as cofactors for enzymes, helping them function properly.

5. Water: Water is essential for many body functions, including transporting nutrients and oxygen to cells, removing waste products, and regulating body temperature.
