It has three steps called glycolysis, the Krebs cycle, and the electron transport chain. Cellular respiration is more efficient than fermentation in the generation of ATP. Although there is a theoretical yield of 38 ATP molecules per glucose during cellular respiration, such conditions are generally not realized because of losses such as the cost of moving pyruvate (from glycolysis), phosphate, and ADP (substrates for ATP synthesis) into the mitochondria. Likewise, is NADH 2.5 or 3 ATP? Cellular respiration. 4 b. anaerobic and aerobic . © copyright 2003-2021 Study.com.
