Question

Cellular respiration occurs in every cell of our bodies. Through this process, we obtain the

energy we need for life. During cellular respiration, oxygen helps in breaking down sugar
molecules into carbon dioxide and water molecules. Which reaction correctly represents the
cellular respiration process? (1 point)

Answer 1

1)The reactants are unlit charcoal, and the products are charcoal that has already burned and released its energy.

2)sugar + oxygen → carbon dioxide + water + energy

3)iron + oxygen → rusted iron + energy

4)an endothermic reaction, because ice absorbs heat to become liquid water

5)The temperature of the reactants is greater than the temperature of the products.
