1. Anaerobic Respiration No oxygen available to accept used electrons

2. How do organisms make ATP if no oxygen is available?

3. Food is ingested Food is modified- broken down Fermentation Lactate Ethanol + CO 2 Fermentation Lactate Ethanol + CO 2 i.Kreb’s Cycle ii.Electron Transport Chain i.Kreb’s Cycle ii.Electron Transport Chain Is Oxygen Present to accept electrons? YES!NO! Aerobic Respiration Anaerobic Respiration

4. 0 No oxygen is present to accept electrons 0 NAD+ is the major output that continues production of ATP. 0 SO HOW IN THE WORLD IS ATP MADE?

5. Glycolysis Review 0 Very Important Process for making ATP 0 Review: converts Glucose  Pyruvate + 2 ATP (net) 0 Used by virtually ALL organisms to produce ATP 0 Does NOT require oxygen

7. Lactic Acid Fermentation 0 Who uses this process? 0 Your Muscle Cells 0 Bacteria such as Lactobacilli 0 Some Fungi 0 Inputs: Pyruvate and NADH 0 Outputs: lactic acid and NAD+ 0 NAD+ re-enters glycolysis to make ATP 0 SLOW PROCESS but still gaining ATP
