Question

animal cells perform functions using energy that is derived from glucose (c₆h₁₂o₆). which molecule is required for animal cells to obtain the most energy possible from a molecule of glucose?
water
oxygen
lactic acid
carbon dioxide

Explanation:

Animal cells perform aerobic respiration to obtain the most energy possible from glucose. Aerobic respiration requires oxygen. Water and carbon dioxide are products of aerobic respiration. Lactic acid is a product of anaerobic respiration (which produces less energy than aerobic respiration).

Answer:

oxygen
