Answer 1

Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants.

Answer 2

Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants.

Answer 3

To determine which statement is correct, we need to understand the concept of activation energy in relation to exothermic and endothermic reactions.

Activation energy is the minimum amount of energy required for a reaction to occur. In an exothermic reaction, the products have a lower energy state than the reactants, meaning energy is released during the reaction. In an endothermic reaction, the products have a higher energy state than the reactants, meaning energy is absorbed during the reaction.

Based on this information, we can deduce that cellular respiration, which is an exothermic reaction, needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Therefore, the correct statement is: "Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants."
