Answer:
A. Aerobic respiration
Explanation:
The cell body of neurons have mitochondria which in turn serve as the site for ATP production. Nerve cells derive their energy by complete oxidation of glucose by the process of aerobic respiration. The enzymes required for aerobic respiration of glucose are present in mitochondria. The ATP molecules produced in cell bodies are delivered to the other parts of neurons to serve as source of energy during conduction of nerve impulse.
