Detailed explanation-1: -After the second turn through the Krebs cycle, the original glucose molecule has been broken down completely. All six of its carbon atoms have combined with oxygen to form carbon dioxide.
Detailed explanation-2: -These six CO2 molecules are given off as waste gas in the Krebs cycle. They represent the six carbons of glucose that originally entered the process of glycolysis. At the end of the Krebs cycle, the final product is oxaloacetic acid.
Detailed explanation-3: -For one glucose molecules, there will be two rounds of Krebs cycle. This is because two molecules of Pyruvic acid are formed from one molecule of glucose during Glycolysis.
Detailed explanation-4: -So the answer for this question is going to be zero. Did you know?
Detailed explanation-5: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
