Detailed explanation-1: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
Detailed explanation-2: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
Detailed explanation-3: -The Krebs cycle is the second phase in cellular respiration. It occurs in the mitochondria in the cell. The number of ATP molecules produced in the Krebs cycle is 2.
Detailed explanation-4: -Two molecules of triose-phosphate produced per molecule of glucose yields 4–6 ATP. These, in addition to the 2 ATP made from glycolysis, gives a total of 6–8 molecules of ATP per glucose molecule.
Detailed explanation-5: -In aerobic respiration, one glucose molecule results in a net ATP gain of 38 ATP. It comprises ATP generated during glycolysis, the link reaction, the TCA cycle, and oxidative phosphorylation in the electron transport system.
