When ATP concentration is low or the respiratory chain is inhibited, the mithcohondria are seen in.

Options

A. Active state
B. Condensed state
C. Orthodox state
D. Both (1) and (2)

Answer

To answer the question "When ATP concentration is low or the respiratory chain is inhibited, the mitochondria are seen in," we need to analyze the conditions affecting the mitochondria's state.

### Step-by-Step Solution:

1. **Understanding Mitochondria**: Mitochondria are known as the powerhouse of the cell, responsible for producing ATP (adenosine triphosphate), which is the energy currency of the cell. They have a double membrane structure and are crucial for cellular respiration.

2. **Low ATP Concentration**: When ATP concentration is low, it indicates that the cell requires more energy. In this state, mitochondria are activated to produce more ATP to meet the energy demands of the cell. Therefore, they are in an active state.

3. **Respiratory Chain Inhibition**: The respiratory chain is a series of complexes in the inner mitochondrial membrane that are essential for ATP production through oxidative phosphorylation. If this chain is inhibited, it can disrupt ATP synthesis. However, the mitochondria will still attempt to produce ATP, which means they remain in an active state, trying to compensate for the lack of energy.

4. **Identifying the Correct State**: Given that both conditions (low ATP and inhibited respiratory chain) lead to an increased demand for ATP production, mitochondria are observed in an active state.

5. **Conclusion**: Therefore, the correct answer to the question is that mitochondria are seen in an **active state** when ATP concentration is low or when the respiratory chain is inhibited.

### Final Answer:
The correct option is **active state**.
