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.

Glycolysis is the process that turns glucose into pyruvate. The energy released from this is then used to make the more readily usable ATP.
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.
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.
Most organisms break down sugar to produce usable energy through the process of cellular respiration, which involves a series of biochemical reactions that release energy stored in glucose molecules. This process occurs in the mitochondria of cells and produces ATP (adenosine triphosphate) as the primary energy currency of the cell.
