Detailed explanation-1: -Oxygen and glucose represent the reactants, while carbon dioxide, water, and energy represent the products.
Detailed explanation-2: -During cellular respiration, the reactants-glucose (sugar) and oxygen-combine together to form new products: carbon dioxide molecules and water molecules. Adenosine triphosphate (ATP) is produced as the form of energy that can be used for other cellular processes.
Detailed explanation-3: -Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane. The starting reactants of cellular respiration include glucose, ATP, and NAD+; and the final products include ATP and H2O.
Detailed explanation-4: -The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Detailed explanation-5: -Glycolysis is the first stage of cellular respiration, and the reactants are one molecule of glucose and two molecules of ATP (adenosine triphosphate). The ATP molecules provide energy so that the reaction can occur.
