Respiration

• Two types of Respiration

  Aerobic, Anaerobic
• Aerobic Respiration breaks down food molecules using oxygen and releases large amounts of energy
• Respiration is the oxidation of food substances to release and produce ATP molecules
• Chemical reaction of Aerobic Respiration

  Glucose + Oxygen ➜ Carbon Dioxide + Water + Large amount of energy
• Anaerobic Respiration is the break down of food substances without oxygen and releases a small amount of energy
• Aerobic Respiration is common in multicellular organisms
• Anaerobic Respiration is common in unicellular organisms
• Anaerobic Respiration has one common pathway: Fermentation
• Two types of Fermentation: Lactic, Alcoholic
• Chemical reaction of Lactic Fermentation

  Glucose ➜ Lactose + Small amount of energy (2 ATP)
• In Lactic Fermentation, NADH transports e- directly to pyruvate to generate lactate

  
• Muscle cells and RBC undergoes lactic fermentation but it is considered inefficient for muscle cells
• We experience muscle soreness because of the accumulation of lactic acid

  False
• We experience muscle soreness because of microscopic trauma

  True
• Lactobacillus is the bacteria in yogurt
• Lactobacillus undergoes lactic fermentation
• In Alcoholic Fermentation, the glucose is converted into ethanol and carbon dioxide
• Chemical reaction of Alcoholic Fermentation

  Glucose ➜ Ethanol + Carbon Dioxide, Small amount of energy (2 ATP)
• In Alcoholic Fermentation, pyruvate releases carboxyl group to be acetaldehyde and will receive 2 NADH e- to produce ethanol
