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 a large amount of energy. Anaerobic respiration occurs without oxygen, also starting with glucose breakdown but in cytoplasm and producing less energy and different end - products like lactic acid or ethanol. Glucose is the starting molecule for both processes. Oxygen is only for aerobic, water is a product of aerobic, and mitochondria are mainly for aerobic.

Answer:

D. glucose
