Answer to Problem 1A
Correct answer:
The ability of the digestive system to break down macromolecules into smaller subunits is hydrolysis. Therefore, option (d) is correct.
Explanation of Solution
Reason for the correct statement:
Hydrolysis is the breakdown of macromolecules into smaller subunit molecules.
Option (d) is given as “hydrolysis”.
The “ability of the digestive system to break down macromolecules into smaller subunits is called as hydrolysis”, it is the right answer.
Hence, option (d) is correct.
Reasons for the incorrect statements:
Option (a) is given as “peristalsis”.
Peristalsis is a rhythmic digestive tract movement that aids in ingestion of food. So, it is a wrong answer.
Option (b) is given as “ingestion”.
Ingestion is when food is taken by the body. So, it is a wrong answer.
Option (c) is given as “absorption”.
Absorption is the uptake of nutrients from lumen of intestinal tract. So, it is a wrong answer.
Option (e) is given as “elimination”
Elimination is the removal of waste material from the body. So, it is a wrong answer.
Hence, options (a), (b), (c) and (e) are incorrect.
The ability of the digestive system to break down macromolecules into smaller subunits is called as the hydrolysis.
