alleryA neurone's mitochondria are damaged while every other organelle stays intact. What does the cell lose?
AIts ability to release energy
BIts ability to make proteins
CIts insulating outer sheath
DIts store of genetic material
Answer & Solution
Correct answer: A. Its ability to release energy
1. Mitochondria are the site of aerobic respiration in any cell.
2. Respiration releases the energy the cell needs, stored as ATP.
3. Damaging them therefore cuts the neurone's energy supply.
4. Protein and enzyme production is the work of the Nissl granules, a separate structure.
5. Confusing mitochondria with Nissl granules, or with the nucleus, was recorded on this question in both directions.
