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 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.

They increase activation energy.
They increase activation energy.
They lower activation energy.
On the other hand, for photosynthesis, which is an endothermic reaction, the required activation energy is typically higher. The products are in a higher energy state than the reactants, so more energy is needed to initiate the reaction and convert the reactants to the higher energy products.
