WebMar 5, 2024 · By breaking the bonds in food molecules, cells release energy to build new compounds. Although some energy dissipates as heat at each energy transfer, much of it is stored in the newly made molecules. Chemical bonds in organic molecules are a reservoir of the energy used to make them. WebEnergy production starts with glycolysis, which generates NADH and pyruvate. Pyruvate goes to the mitochondria to make more NADH (or FADH2, which is similar to NADH) in the Krebs Cycle. NADH is used to power the electron transport chain, which gives most of the energy the cell uses.
