Select the incorrect statement from the following :
(i) Biomolecules are in metabolic flux in the living state .
(ii) Living process is a constant effort to prevent falling into equilibrium
(iii) Metabolism provides a mechanism for the production of energy
(iv) Living state and metabolism is synonymous

Options

A. All except (i)
B. All except (ii)
C. All are incorrect
D. All are correct

Answer

To determine the incorrect statement from the options provided, we will analyze each statement one by one:

1. **Statement (i)**: "Biomolecules are in metabolic flux in the living state."
- **Analysis**: This statement is correct. In living organisms, biomolecules are constantly undergoing metabolic processes, which include synthesis and breakdown. This dynamic state is referred to as metabolic flux.

2. **Statement (ii)**: "Living process is a constant effort to prevent falling into equilibrium."
- **Analysis**: This statement is also correct. Living organisms maintain a state of homeostasis and are constantly exchanging materials with their environment to avoid reaching equilibrium, which would lead to a cessation of metabolic activities.

3. **Statement (iii)**: "Metabolism provides a mechanism for the production of energy."
- **Analysis**: This statement is correct as well. Metabolism encompasses all biochemical reactions in the body, including catabolic reactions that break down molecules to release energy, primarily through processes like respiration.

4. **Statement (iv)**: "Living state and metabolism is synonymous."
- **Analysis**: This statement is incorrect. While metabolism is a characteristic of living organisms, the terms "living state" and "metabolism" are not synonymous. Metabolism refers specifically to the biochemical processes that occur within a living organism, but a living state can also encompass other factors such as homeostasis, growth, and reproduction, which are not solely defined by metabolic reactions.

**Conclusion**: The incorrect statement is **(iv)**: "Living state and metabolism is synonymous."
