Choose the false statement -

Options

A. The living state is a non-equilibrium steady state to be able to perform work
B. The constant flow of material or energy in and out of cell prevent from reaching equilibrium
C. Living state and metabolism are synonymous
D. None

Answer

To solve the question of identifying the false statement among the given options, we will analyze each statement based on our understanding of the concepts of living organisms, metabolism, and equilibrium.

### Step-by-Step Solution:

1. **Understanding the Living State**:
- The living state is often described as a non-equilibrium steady state. This means that living organisms maintain a state where they are not in equilibrium, allowing them to perform work and carry out metabolic processes.

**Hint**: Consider how living organisms maintain their functions and energy levels.

2. **Metabolism and Non-Equilibrium**:
- For an organism to stay alive, it must engage in metabolic reactions. These reactions require a constant input of energy and materials, which is only possible if the organism is in a non-equilibrium state. If it reaches equilibrium, metabolic processes would cease, leading to death.

**Hint**: Think about what happens to living cells when they stop metabolizing.

3. **Synonyms of Living State and Metabolism**:
- The statement that living state and metabolism are synonyms suggests that if an organism is alive, it must be undergoing metabolism. This is true because metabolism encompasses all biochemical reactions that sustain life.

**Hint**: Reflect on the definition of metabolism and its role in life processes.

4. **Evaluating the Statements**:
- After analyzing the statements, we find that:
- The first statement about the living state being a non-equilibrium steady state is true.
- The second statement regarding metabolism requiring a non-equilibrium state is also true.
- The third statement equating living state with metabolism is true as well.

5. **Conclusion**:
- Since all the statements provided are true, the answer to the question "Choose the false statement" is that there is no false statement among the options given. Therefore, the correct option is that none of the statements are false.

### Final Answer:
All statements are true. The correct option is option 4: None.
