The Role of Enzymes Quick Check 1 of 51 of 5 Items Question Cellular respiration is an exothermic reaction and photosynthesis is an endothermic reaction. How does the required activation energy compare for these two reactions?(1 point) Responses Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Photosynthesis needs a higher amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Photosynthesis needs a higher amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Cellular respiration needs a higher amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Cellular respiration needs a higher amount of energy to activate the reaction because the products are at a lower energy state than the reactants. Photosynthesis needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants.

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.
