HUMAN NUTRITION

Detailed explanation-1: -The part of the digestive system that chemically initiates the digestion of proteins is the stomach.

Detailed explanation-2: -Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.

Detailed explanation-3: -Enzymatic digestion of proteins begins in the stomach with the action of the enzyme pepsin. Proteins are large globular molecules, and their chemical breakdown requires time and mixing.

Detailed explanation-4: -The body needs a constant supply of energy in order to survive. The minimum level of energy required just to perform chemical reactions in the body and maintain essential activities of the central nervous system, heart, kidney, and other organs is known as the basal metabolic rate (BMR).

Detailed explanation-5: -Digestion of protein starts in stomach of human digestive tract. When we consume food, digestion is a crucial process that must occur at regular intervals. Digestion necessitates the use of specialised enzymes that act on specific compounds. The enzyme pepsin is responsible for the digestion of proteins.
