ANATOMY

Detailed explanation-1: -Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins.

Detailed explanation-2: -Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules.

Detailed explanation-3: -Hydro-stands for water while-lysis stands for the breaking down of molecules. Hence, hydrolysis is the chemical breakdown of a substance using water. During hydrolysis, a macromolecule is broken down into simpler units. It helps the small intestine to absorb nutrients more effectively.

Detailed explanation-4: -Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.

Detailed explanation-5: -Enzymatic hydrolysis is a process in which hydrolase-type enzymes cleave a substrate into reaction products using a water molecule. The reaction conditions (temperature, pH, etc.) are specific to each enzyme for its optimal activity.
