Introduction:
Food is broken down by the body before it is absorbed. The breaking of food is carried out by enzymes and acids present in the stomach and intestine. This process is called digestion.
Answer to Problem 1TY
Correct answer:
The process of enzymatically breaking down large molecules into smaller molecules that can be used by cells is called as digestion. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
Breaking down of food into smaller particles so that it can be absorbed easily is known as digestion. It can be broken down either enzymatically or mechanically during digestion.
Option d is given as “digestion”.
The breakdown of food starts from mouth and absorption takes place in the intestine. Hence, the correct answer is option d.
Reasons for incorrect answers:
Option a. is given as “absorption”.
Absorption is the process in which the nutrients from the digested food is absorbed or taken up by the cells to transport throughout the body. Hence option a. is incorrect.
Option b. is given as “secretion”.
Secretion is a process in which some biological substances are released to promote biological processes. Hence option b. is incorrect.
Option c. is given as “ingestion”.
Ingestion refers to engulfment or swallowing of food or water into the body. Hence option c. is incorrect.
Option e. is given as “egestion”.
Egestion refers to the excretion of undigested food materials from the body. Hence option e. is incorrect.
Hence options, a, b, c, and e are incorrect
Thus, digestion is a process in which food is enzymatically broken down into smaller components.
