DENDROLOGY

Detailed explanation-1: -Oxygen and glucose represent the reactants, while carbon dioxide, water, and energy represent the products. Reactants are the molecules that combine to start the reaction. Products are those molecules produced during cellular respiration.

Detailed explanation-2: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-3: -Glucose is the molecule normally used for respiration-it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules. Respiration is a series of chemical reactions, but this equation summarises the overall process.
