Both the reactants and products of photosynthesis contain carbon (C), hydrogen (H), and oxygen (O), but the products contain greater energy than the reactants. How can the products of photosynthesis have greater energy than the reactants?

• because the particles in the products move faster than in the reactants
• because the reaction increased the masses of the nuclei in the products.
• because after the products were exposed to sunlight their electical charges increased.
• because more energy is stored in the chemical bonds of the products than the reactants.

• sugar concentration in the water
• carbon dioxide concentratiion in the air
• None of the above

The diagram shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.
Which statement describes how photosynthesis and cellular respiration are related?

• Oxygen is a PRODUCT made during cellular respiration and stored during photosynthesis.

• Carbon dioxide and water are REACTANTS for photosynthesis and PRODUCTS for cellular respiration

• Photosynthesis releases the energy that is stored during the process of cellular respiration.
• Glucose is used as a REACTANT during cellular respiration to the PRODUCTS of food that is broken down during photosynthesis.
