Detailed explanation-1: -The raw materials required for aerobic cellular respiration are respiratory substrates (glucose, fatty acids, amino acids, or organic acids) and oxygen but in the case of anaerobic respiration raw material is respiratory substrate only.

Detailed explanation-2: -The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.

Detailed explanation-3: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide.

Detailed explanation-4: -Glucose is used in the very first step of cellular respiration, as it represents the main substrate metabolized during glycolysis. After glucose is broken down into pyruvate, the pyruvate molecules are transformed into acetyl CoA.

Detailed explanation-5: -Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
