2.4 Respiration

• What is produced in large quantities during aerobic respiration?

  ATP

• What is respiration in biological terms?

  Release energy from food
• Anaerobic respiration occurs in the absence of oxygen.

  True
• How many ATP molecules are produced per glucose molecule in aerobic respiration?

  36-38 ATP
• The oxygen requirement is a key difference between aerobic and anaerobic respiration
• The citric acid cycle occurs in the mitochondria
• Aerobic respiration is the most efficient form of respiration.


  True
• Respiration is the process by which cells release energy from food molecules through a series of chemical reactions
• What are the byproducts of aerobic respiration?

  Carbon dioxide and water
• Steps in aerobic respiration:

  1️⃣ Glycolysis

  2️⃣ Citric acid cycle

  3️⃣ Electron transport chain
• Why is aerobic respiration more efficient than anaerobic respiration?

  Produces more ATP
• Aerobic respiration produces up to 36-38 ATP
