ATPs are synthesized by

Options

A. mitochondria
B. chloroplast
C. golgi bodies
D. 1 and 2

Answer

**Step-by-Step Solution:**

1. **Understanding ATP**: ATP stands for adenosine triphosphate, which is the primary energy carrier in all living organisms. It is crucial for various cellular processes.

2. **Identifying the Sites of ATP Synthesis**:
- **Mitochondria**: The first option is mitochondria. Mitochondria are known as the powerhouse of the cell. They are responsible for oxidative phosphorylation, where glucose metabolism occurs, leading to the synthesis of ATP.
- **Chloroplasts**: The second option is chloroplasts. Chloroplasts are involved in photosynthesis, where light energy is converted into chemical energy, resulting in the production of ATP.
- **Golgi Bodies**: The third option is Golgi bodies. Golgi bodies are primarily involved in the packaging and transport of proteins, and they do not synthesize ATP.
- **Combination of Mitochondria and Chloroplasts**: The last option states both mitochondria and chloroplasts. Since both organelles are involved in ATP synthesis, this option is also correct.

3. **Conclusion**: Based on the analysis of each option, ATP is synthesized by both mitochondria and chloroplasts.

**Final Answer**: ATPs are synthesized by mitochondria and chloroplasts.
