Final answer:
Mitochondria and chloroplasts are the organelles involved in energy conversion, with mitochondria producing ATP through cellular respiration, and chloroplasts converting solar energy to chemical energy through photosynthesis.
Step-by-step explanation:
The organelles involved in energy conversion are mitochondria and chloroplasts. Mitochondria are known as the powerhouse of the cell because they produce adenosine triphosphate (ATP), which is the cell's main energy-carrying molecule. They achieve this through a series of biochemical reactions along the inner membrane, called cristae, where cellular respiration takes place. This process requires oxygen, incorporates nutrients like glucose, and produces carbon dioxide as a waste product. Chloroplasts, on the other hand, are present in plant cells and some algae, and are responsible for photosynthesis, where they convert solar energy into chemical energy stored in glucose.
Per the options provided, the correct answer to the question 'Which organelles are involved in energy conversion?' would be C) Mitochondria and chloroplasts.
