Mitochondria and chloroplasts are concerned with the transfer of cellular energy. Is this statement correct ?

Options

A. Yes, it is correct
B. No, mitochondria but not chloroplast
C. No, neither of them
D. No, chloroplasts are but not mitochondria

Answer

To determine whether the statement "Mitochondria and chloroplasts are concerned with the transfer of cellular energy" is correct, we can analyze the roles of both organelles in cellular processes.

### Step-by-Step Solution:

1. **Understanding Mitochondria**:
- Mitochondria are known as the "powerhouses" of the cell. They are primarily involved in cellular respiration, a process that converts biochemical energy from nutrients into adenosine triphosphate (ATP), which is the energy currency of the cell.
- During cellular respiration, mitochondria utilize oxygen to break down glucose and produce ATP, along with carbon dioxide and water as byproducts.

2. **Understanding Chloroplasts**:
- Chloroplasts are the organelles responsible for photosynthesis in plant cells and some algae. During photosynthesis, chloroplasts convert light energy, usually from the sun, into chemical energy stored in glucose.
- While chloroplasts do not directly produce ATP in the same way mitochondria do, they do generate glucose, which can later be converted into ATP through cellular respiration in mitochondria.

3. **Analyzing the Statement**:
- The statement claims that both mitochondria and chloroplasts are concerned with the transfer of cellular energy.
- Mitochondria definitely play a crucial role in energy transfer through ATP production.
- Chloroplasts contribute to energy transfer indirectly by producing glucose, which can be used in cellular respiration to generate ATP.

4. **Conclusion**:
- The statement is partially correct. Mitochondria are directly involved in the transfer of cellular energy, while chloroplasts play a role in energy conversion (from light to chemical energy) but are not directly involved in ATP production.
- Therefore, the correct interpretation of the statement would be that it is not entirely accurate to say both organelles are concerned with the transfer of cellular energy in the same way.

### Final Answer:
The statement "Mitochondria and chloroplasts are concerned with the transfer of cellular energy" is **not entirely correct**. Mitochondria are directly involved in energy transfer, while chloroplasts contribute indirectly.
