The net gain of energy from one molecule of glucose through cellular respiration is approximately 36 to 38 ATP molecules, depending on the efficiency of the process and the type of cell. This energy is produced during glycolysis, the Krebs cycle, and oxidative phosphorylation. However, the actual yield can vary between organisms and conditions, but this range is commonly cited in the context of aerobic respiration.
Two, net.
During glycolysis, a net gain of two ATP molecules is produced per glucose molecule. In the citric acid cycle, a total of 2 ATP molecules are produced per glucose molecule. Finally, during oxidative phosphorylation, approximately 34 ATP molecules are produced per glucose molecule through the electron transport chain. This results in a total of about 38 ATP molecules gained per glucose molecule during cellular respiration.
Every glucose molecule that enters glycolysis yields two molecules of pyruvate, two molecules of ATP (net gain), and two molecules of NADH. Glycolysis occurs in the cytoplasm and is the first step in both aerobic and anaerobic respiration. Additionally, it involves a series of enzymatic reactions that convert glucose into pyruvate while extracting energy.
4 molecules of ATP are produced per molecule of glucose in glycolysis, but 2 are needed (used, degraded, etc.) to start the reaction, so there is really only a net gain of 2 ATP in the process of glycolysis.
Most of the energy from glucose is stored in the form of ATP (adenosine triphosphate) at the end of glycolysis. During this metabolic pathway, glucose is broken down into pyruvate, producing a net gain of two ATP molecules and two NADH molecules, which can further contribute to energy production in cellular respiration. The high-energy bonds in ATP allow cells to harness this energy for various biochemical processes.
It isn't stored in any specific place of the molecule. The chemical potential energy is the result of a possible "gain" of energy when the atoms in a glucose molecule combine with other atoms. Thus, the glucose and the other atoms, separately, are at a "higher energy level".
During glycolysis, the overall gain of ATP per glucose molecule is 2. While glycolysis produces 4 ATPs, it uses 2 ATPs in the process.
No, an oxidized molecule has already lost electrons and is in a lower energy state. In order to gain energy, a molecule would need to be reduced by gaining electrons.

Glycolysis produces a net gain of 2 ATP molecules and 2 NADH molecules per glucose molecule. Each ATP molecule provides about 7.3 kilocalories of energy.

Two molecules of ATP are consumed in the energy investment phase, while four molecules of ATP and two molecules of NADH are produced in the energy payoff phase. This results in a net gain of two molecules of ATP per molecule of glucose oxidized to pyruvate.
