Question

`Choose the correct statement: (1) Metabolism include constructive reactions only. (2) Anabolic reactions are destructive in nature. (3) Catabolic reaction are constructive in nature. (4) Metabolic reactions can be demonstrated outside the body in cell-free systems.`​

Answer 1

Answer:

Option 4

Explanation:

because 1) metabolism include both constructive and destructive

2) anabolic reactions are constructive

3) catabolic reactions are destructive

Answer 2

Answer:

The correct statement is - (4) Metabolic reactions can be demonstrated outside the body in cell-free systems.

Explanation:

• Metabolism is the sum of all the reactions that occur in a living organism. It encompasses both catabolism and anabolism.

• Catabolism, also known as destructive metabolism, is the process of breaking down molecules to release energy. It encompasses all breakdown reactions involving the formation of simpler substances from complex substances. During respiration, for example, glucose degrades to release energy and produce carbon dioxide and water.

• Anabolism, also known as constructive metabolism, is the process by which complex substances are synthesized. It includes all of the reactions that are building up, and energy is required during this process. Carbon dioxide, for example, forms sugars using solar energy during photosynthesis.

• Metabolism is a distinguishing feature of living organisms and cannot be observed in non-living things. It can be demonstrated in cell-free systems outside of the body. In vitro isolated metabolic reactions occur in non-living things but are living reactions.

Therefore from above Bold highlights we can summarise-

• Option(4) Metabolic reactions can be demonstrated outside the body in cell-free systems is the Correct statement.

• Option 1,2,3 are incorrect and reason has been included in above bold highlighted underlined paragraphs.
