Introduction:
The catabolic processes and anabolic processes are seen in many of the cellular activities. The example of catabolic processes is
Answer to Problem 1MC
Correct answer:
The breaking of large molecule to smaller molecules is known as catabolism.
Therefore, option (c) is correct.
Option (c) is given as “catabolism only”.
Explanation of Solution
Justify reasons for the correct statement:
The catabolism and anabolism are two pathways. The catabolism is the process of breaking down large complex molecules into simpler substances. As, the large molecules are converted into smaller ones, hence, it is known as catabolism.
Hence, option (c) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “anabolism only”.
The anabolism is the combination of smaller molecules into larger molecules. Hence, it is a wrong answer.
Option (b) is given “both anabolism and catabolism (amphibolic)”.
The breakdown of large molecule into smaller ones is a catabolism process but not an anabolism process. Hence, it is a wrong answer.
Hence, options (a) and (b) are incorrect.
When the small molecules are obtained from the breakdown of large molecules it is known as catabolism process.
