Question

The term metabolism refers to a _____

• A. Release or gain of energy
• B. Catabolism of a reaction
• C. Gain of energy
• D. Release of energy

Answer 1

The correct option is A

Release or gain of energy

The correct option is option A.

Explanation of the correct option:

1. Metabolism is defined as the sum of all chemical events that occur at the cellular level with the ultimate purpose of providing energy.
2. Nutrients are divided into fundamental units that are subsequently employed in various pathways and structures.
3. This process takes place inside the body via numerous channels.
4. It is critical for the body's operations such as growth, reproduction, and stimulus-response.
5. The metabolism is responsible for all bodily activities.
6. The fundamental concept is to transform food into energy.
7. It combines catabolism and anabolism.
8. Catabolism produces energy, whereas anabolism consumes energy.

Explanation of the incorrect options:

Option B:

1. Catabolism is the breakdown of molecules in the course of metabolism.
2. This is the primary mechanism that results in energy release.
3. Both catabolism and anabolism are involved in the metabolic process.

Option C:

1. Gain of energy occurs during an anabolic chemical reaction in which energy is required for synthesizing the complex organic compounds from simpler compounds.
2. These reactions are called endergonic reactions(consume more energy than they release).

Option D:

1. The release of energy occurs during a catabolic chemical reaction in which energy is released by the breakdown of complex organic compounds into simpler compounds.
2. These reactions are also called exergonic reactions ( release more energy than they consume).

Final Answer: the term metabolism refers to a release or gain of energy.
