  2. Vocab • Cellular respiration- the oxidation of organic compounds to extract energy from chemical bonds. • Nicotinamide adenine dinucleotide- a molecule that becomes reduced to NADH as it carries high energy electrons. • Aereobic respiration- the process that results in the complete oxidation of glucose. • Anaerobic respiration- The use of electron transport to generate a protein gradient. • Electron transport chain- the electrons are passed to another set of electron carriers. • Glycolysis- the initial breakdown of glucose. • ATP Synthase- An enzyme that synthesizes ATP.

  3. Glycolysis • Priming changes glucose into an easily cleaved form • - Step A: Glucose priming • - Step B: Cleavage and rearrangement • ATP is synthesized by substrate-level phosphorylation • - Step C: Oxidation • - Step D: ATP generation

  4. Glycolysis: The Reactions

  5. Krebs Cycle • The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH), as well as some ATP

  6. Krebs Cycle

  7. Electron Transport Chain • The electron transport chain produces a proton gradient. • The gradient forms as electrons move through electron carriers. • Chemiosmosis utilizes the electrochemical gradient to produce ATP. • ATP synthesis is a molecular rotary motor.
