Answer:Cellular Respiration
Explanation:
Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
