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: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-3: -Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

Detailed explanation-4: -What is photosynthesis? Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-5: -The process of aerobic respiration completely breaks down glucose into carbon dioxide and water, whereas anaerobic respiration incompletely breaks down glucose into alcohol (alcohol fermentation) or lactic acid (lactic acid fermentation).
