Question

plzz provide me an explanation on digestion

Answer 1

HERE IS YOUR ANSWER !!
________________________
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.

Answer 2

Hey mate here's your answer:

The food of most organisms consists of large insoluble molecules which cannot be absorbed by the organisms body in this form. So, before the food can be used by the organism for various functions like getting energy or for growth, it must be broken down into small, water soluble molecules which can be absorbed by the body. The process in which the food containing large, insoluble molecules is broken down into small, water soluble molecules (which can be absorbed by the body) is called digestion.
