2. Why is ATP a better immediate energy source than glucose?

  • ATP is closer to the organelles that need it
  • Each ATP molecule releases less energy than glucose molecules, meaning that less heat is released, which could denature cells and enzymes and ATP is broken down in one reaction (hydrolysis), releasing energy immediately
  • Glucose contains less energy

3. What is produced during anaerobic respiration?

  • Lactate/ethanol, CO2 (in plants) and little ATP
