Question

What is digestion? Mention the two types.

Answer 1

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.

Intracellular Digestion: The digestion that occurs inside the cell is called intracellular digestion.
Extracellular Digestion: The digestion that occurs outside the cell is called extracellular digestion
