Beta oxidation of both Fatty acids produces both FADH2 and NADH. How many ATP can be made by oxidative phosphorylation from the FADH2 and NADH produced by one turn of the Fatty acid spiral? Answer: 5, Don't have a clue why.
Oxygen is NOT needed to produce ATP. This is only true for Oxidative Phosphorylation. Substrate Level Phosphorylation does not require ATP at all. While ATP can be produced without oxygen via a process called anaerobic respiration, aerobic respiration is a much more efficient means of ATP production.
