Question

which is required for both anaerobic respiration and aerobic respiration?
oxygen
water
mitochondria
glucose

Explanation:

Aerobic respiration uses oxygen to break down glucose in mitochondria to produce water and energy. Anaerobic respiration occurs without oxygen, often in the cytoplasm, and also starts with glucose breakdown. Glucose is the starting - point for both processes. Oxygen is only for aerobic respiration, water is a product of aerobic respiration, and mitochondria are mainly involved in aerobic respiration.

Answer:

D. glucose
