Fermentation can be defined as the process that involves partial breakdown of sugar molecules into alcohol and lactic acid, in the absence of oxygen. It occurs in many bacterial cells, yeasts, and starved muscle cells. Whereas respiration involves complete breakdown of sugar molecules into carbon dioxide and water, in the presence of oxygen. It occurs in all living organisms. Respiration provides a large amount of energy as compared to fermentation as respiration produces 36 ATP molecules and 2 ATP molecules per glucose molecule.
Hence, the correct answer is 'option C - cellular respiration produces more ATP molecules than fermentation.'
