Freshly harvested apples contain living cells that continue to respire. A researcher stores equal masses of apples at 5 ∘C5\ ^\circ\text{C}5 ∘C and 20 ∘C20\ ^\circ\text{C}20 ∘C. Both batches receive enough oxygen for aerobic respiration. The apples at 5 ∘C5\ ^\circ\text{C}5 ∘C take up less oxygen per hour than the apples at 20 ∘C20\ ^\circ\text{C}20 ∘C.
Suggest why the apples at 5 ∘C5\ ^\circ\text{C}5 ∘C take up less oxygen per hour.
