What this topic is really about
Mitochondria are known as the powerhouses of the cell because they are the site of aerobic respiration, which generates ATP to power cellular activities. In contrast, protein synthesis is carried out by ribosomes, making that option incorrect for this organelle.
During photosynthesis, plants use light energy to convert carbon dioxide and water into glucose, releasing oxygen into the atmosphere as a waste by-product. Carbon dioxide is a reactant required for the process to begin, rather than a product that is released.

An exam-style question, fully explained
Mitochondria are mainly involved in:
- Identify what the question tests: Mitochondria are mainly involved in:.
- Mitochondria are known as the powerhouses of the cell because they are the site of aerobic respiration, which generates ATP to power cellular activities.
- In contrast, protein synthesis is carried out by ribosomes, making that option incorrect for this organelle.
Traps the examiner sets
- In contrast, protein synthesis is carried out by ribosomes, making that option incorrect for this organelle.
- A chromosome is incorrect because it is a much larger structure made of tightly coiled DNA containing hundreds or thousands of individual genes.
- The pulmonary artery is incorrect because it carries deoxygenated blood away from the heart to the lungs to receive oxygen.
