Question

Choose the correct answers from the alternatives given .
All the biochemical pathways in a cell constitute

• A. Coupling reactions
• B. Endergonic reactions only
• C. Exergonic reactions only
• D. Metabolism

Answer 1

The correct option is D Metabolism

There are various biochemical reactions taking inside a cell. Some of these reactions may result in absorption of energy (called as endergonic reactions) or release of energy (called as exergonic reactions). Often both these types of reactions are coupled, to get the energy to those endergonic reactions, they are paired up with energy-releasing exergonic reactions (known as coupling reactions). Although, there are a wide variety of reactions taking place inside the body apart from these reactions. Metabolism is a term that is used to describe all these biochemical reactions involved in maintaining the living state of the cells and the organism.

So, the correct option is 'Metabolism'.
