Cellular Respiration Cellular Respiration is almost the exact opposite process of photosynthesis. The reaction for Cellular Respiration follows: C6H12O6 + H2O → 6CO2 + 6H2O Energy
Stages of Cellular RespirationStage 1: Glycolysis Stage 2: Aerobic Respiration
Glycolysis Anaerobic Process – does not require oxygenGlucose is broken down in the cytoplasm Two molecules of ATP and NADH are formed for each glucose molecule broken down
Glycolysis (continued)The NADH are converted into Pyruvate molecules Why is the net gain two ATP molecules instead of four in the process?
Aerobic Respiration There are two parts of Aerobic Respiration:Kreb Cycle Electron Transport
Kreb Cycle Pyruvate reacts with oxygen to give off energy and form carbon dioxide Also known as the citric acid cycle
Electron Transport Where most ATP is producedHigh energy electrons and hydrogen ions from the Kreb cycle are used to convert ADP to ATP What is different for cellular respiration in prokaryotics?
Anaerobic RespirationRespiration in the absence of oxygen Fermentation – glycolysis in the absence of oxygen Lactic Acid Fermentation Alcohol Fermentation
Lactic Acid FermentationEnzymes convert pyruvate into lactic acid Occurs in human cells Used by microorganisms that produce foods (cheese, yogurt, sour cream)
Alcohol Fermentation Pyruvate converted to ethyl alcohol and carbon dioxide Occurs in yeast and some bacteria
