Detailed explanation-1: -ATP is not used in the Krebs Cycle, and Its process occurs in the presence of oxygen. It contains Respiratory substrate acetyl coenzyme (A). The Krebs produced 24 ATP molecules from the glucose molecule in the cycle.
Detailed explanation-2: -Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose. Although fermentation produces less ATP, it has the advantage of doing so very quickly.
Detailed explanation-3: -There’s a net production of 1 or 2 ATP molecules during the alcohol and lactic acid fermentation process. Fermentation is an anaerobic process, so it’s able to break down glucose without oxygen. This is the glycolysis process and will yield two ATP, two pyruvate molecules, and two NADH.
Detailed explanation-4: -Glycolysis and Kreb cycle produce reducing compounds NADH, FADH2 which are then oxidized in the presence of oxygen by the process of chemiosmosis to produce a large amount of ATPs.
