34 ATP molecules are produced by the end of the electron transport chain.
Electron transport has the greatest number of ATP molecules.
After glycolysis (the splitting of one glucose molecule, first step in cellular respiration in the mitochondria of a cell) the Krebs cycle, and going through the electron transport chain and ATP synthase...one glucose molecule can yield 38 ATP molecules.
1 This isn't even technically true. One GTP molecule is produced which produces one ATP molecule. The Krebs cycle produces tons of energy, but not in the form of ATP directly. The Krebs cycle (or TCA cycle) results in reducing potential molecules; NADH and FADH2 specifically. These molecules are shuttled through the electron transport chain to produce energy. 3 NADH molecules and 1 FADH molecule is produced for every turn of the Krebs cycle. One molecule of glucose will result in two turns of the Krebs cycle because two pyruvate molecules are the result of one glucose molecule (pyruvate if fed into the Krebs cycle after it is converted into acetyl-CoA). So, one glucose molecule = 6 NADH and 2 FADH molecules (and 2 GTP molecules) In the electron transport chain 1 NADH molecule = 3 ATP. 1 FADH2 molecule = 2 ATP. From here the math is pretty straight forward 6 NADH molecules = 18 ATP 2 FADH molecules = 4 ATP 2 GTP molecules = 2 ATP If you ever read something saying the number of ATP molecules produced from a glucose molecule is between 30-38 ATP do not be confused. This is simply the number for: glycolysis, TCA cycle, and oxidative phosphorylation (electron transport chain) added together. We only get about 30 ATP molecules out of it though because the process is not perfect. Source: Biomed degree.

Electron transport chains
NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.
36-38 molecules of adenosine triphosphate (ATP) are produced from one molecule of glucose during aerobic respiration. 32-34 molecules of ATP are produced from the electron transport chain. Glycolysis produces 2 molecules of ATP. The Krebs cycle produces 2 molecules of ATP.
Majority of ATP molecules are produced in mitochondria, via F1-F0 particles, through electron transport system.

directly, without using the electron transport chain there is one ATP per turn of the Krebs cycle, and two turns per glucose molecule.
Depending on what molecule was used to pass the electron, the number varies from 32 to 34.
