Organic molecules like glucose, fatty acids, and amino acids are broken down through glycolysis and Kreb's cycle to produce usable energy in the form of ATP. In glycolysis, glucose is metabolized to produce pyruvate, which then enters the Kreb's cycle to generate high-energy molecules like NADH and FADH2. These molecules carry electrons to the electron transport chain, where ATP is generated through oxidative phosphorylation.
The majority of the usable energy generated during glycolysis, acetyl CoA formation, and the Krebs cycle is stored in the high-energy phosphate bonds of ATP and NADH molecules. These molecules carry the energy to the electron transport chain, where it is used to produce more ATP through oxidative phosphorylation.
to produce usable energy
Glycolysis is the process that turns glucose into pyruvate. The energy released from this is then used to make the more readily usable ATP.

A process that derives energy from organic molecules in the presence of oxygen is cellular respiration. During this process, glucose and other organic compounds are oxidized to produce carbon dioxide, water, and adenosine triphosphate (ATP), which serves as the energy currency of the cell. Cellular respiration occurs in several stages, including glycolysis, the Krebs cycle, and the electron transport chain. This process is essential for aerobic organisms as it efficiently converts biochemical energy into a usable form.
The process that transforms energy in food molecules to usable energy is called cellular respiration. During cellular respiration, glucose molecules in food are broken down in cells to produce ATP (adenosine triphosphate), which is the form of energy that cells can readily use to power their functions.
Cellular respiration of complex carbohydrates is primarily referred to as glycolysis, which is the first step in the process. During glycolysis, glucose, a simple sugar derived from complex carbohydrates, is broken down to produce energy in the form of ATP. This process occurs in the cytoplasm of the cell and is followed by the Krebs cycle and oxidative phosphorylation, which further generate ATP using the products of glycolysis. Overall, cellular respiration transforms the stored energy in carbohydrates into usable energy for the cell.
Cells can release energy in two basic processes: Cellular respiration and fermentation. Cellular respiration requires oxygen but fermentation does not. Cellular respiration releases MUCH more usable energy then fermentation does.
Cellular Respiration, which can be anaerobic or aeorobic. Aeorobic respiration includes glycolysis (in the mitochondrion), the Krebs cycle (also in the mitochondrion), and the electron transport chain on the inter-membrane of the mitochondrion.
