NADH and FADH2. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration. The starting molecules consist of the biological molecules with carbohydrates (monosaccharides) as the first choice. Cellular respiration is an aerobic (requires oxygen) process, while fermentation is an anaerobic (occurs without oxygen) process. 3 NADH and 1 FADH2 Compare and contrast the role of fermentation and cellular respiration in the actual production of ATP. Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Fermentation. In this stage, two ATP molecules are used and four ATP molecules are made, so it makes a sum of two ATP molecules.

Cellular respiration is a process in organisms that releases energy by breaking down sugar molecules. CO 2 is released as a result of _____. Respiration is the most common energy yielding process in all organisms; the prerequisite being the presence of oxygen, and hence, referred to as aerobic cellular respiration. Fermentation does not require oxygen, therefore it is an Anaerobic process. Summary The cells of most living things produce ATP from glucose by aerobic cellular respiration, which uses oxygen. Anaerobic respiration ( Fermentation ) is a process by which the living organism obtains energy from the food molecule ( glucose ) in the absence or lack of oxygen by the help of special enzymes and this produces a small quantity of energy ( 2ATP molecules ) .
