3.2 How is energy transformed?

Select the correct following pairings:

• If the reactants are higher in chemical potential energy than the products, energy is released by the system during the reaction. The reaction is exothermic.

• If the reactants are lower in chemical potential energy than the products, energy is absorbed from the surroundings during the reaction. The reaction is exothermic.

• If the reactants are higher in chemical potential energy than the products, energy is released by the system during the reaction. The reaction is endothermic.

• If the reactants are lower in chemical potential energy than the products, energy is absorbed from the surroundings during the reaction. The reaction is endothermic.

What happens in cellular respiration?

• Your cells breathe

• Carbon dioxide and water combine with light energy to reduce glucose and oxygen

• It is an endothermic reaction

• Glucose and oxygen react to form carbon dioxide and water.
