What are the stages of cell respiration?
• Cells extract energy from glucose by breaking the bonds between to the high-energy bonds of ATP. • In glycolysis, a six-carbon glucose is broken in half, forming two molecules of pyruvate, each with three carbon atoms. • The fourth stage of cellular respiration is oxidative phosphorylation. • During phosphorylation, the energy released from the breaking of the carbon-carbon and carbon hydrogen bonds in glucose is transfer to phosphorus-oxygen bonds in ATP • What is oxidation? • A molecule that accepts an electron is called an electron acceptor, or oxidizing agent. • A molecule that donates an electron is called an electron donator, or reducing agent. • Coenzymes are organic molecules that are necessary participants in certain in certain enzyme reactions, often as electron donors or acceptors. • Citric Acid cycle • The breakdown of complex molecules is catabolism. • The synthesis of complex molecules is catabolism. • Which molecules serve as electron carriers? • The electrons from NAD
