Question

1. explain do your body cells always use cellular respiration to break down glucose? explain your answer.

Explanation:

Body cells do not always use cellular respiration to break down glucose. Cellular respiration is an aerobic process (requires oxygen). When oxygen is limited (e.g., during intense exercise in muscle cells), cells can use fermentation (anaerobic process) to break down glucose. In humans, lactic acid fermentation occurs, where glucose is partially broken down to produce lactic acid and a small amount of ATP (energy).

Answer:

No, body cells do not always use cellular respiration to break down glucose. When oxygen is scarce (e.g., during intense exercise in muscle cells), fermentation (specifically lactic acid fermentation in humans) is used instead.
