Which organelle is responsible for producing the energy for cellular processes?

• A. Mitochondria
• B. Golgi apparatus
• C. Chloroplasts
• D. Ribosomes

Answer: (A)

Verified step by step guidance

1. Begin by understanding the function of each organelle listed in the options. This will help you identify which one is responsible for energy production.
2. The mitochondria are known as the 'powerhouses' of the cell. They are responsible for producing ATP (adenosine triphosphate), the energy currency of the cell, through a process called cellular respiration.
3. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. It is not directly involved in energy production.
4. Chloroplasts are found in plant cells and are responsible for photosynthesis, converting light energy into chemical energy stored in glucose. While they produce energy, they do so in a different context than mitochondria.
5. Ribosomes are the sites of protein synthesis in the cell. They translate mRNA into polypeptide chains but do not produce energy for cellular processes.
