What to Focus On

  • Cellular respiration is an exergonic (energy-releasing) process.
  • It involves the oxidation of food molecules like glucose.
  • Enzymes catalyze each step of respiration.

  • Occurs in the cytosol.
  • Does not require oxygen.
  • One glucose molecule yields two pyruvate molecules.

  • Pyruvate is converted to acetyl CoA in the mitochondrial matrix.
  • Krebs cycle is amphibolic — involved in both breakdown and synthesis of molecules.
  • One turn produces 3 NADH, 1 FADH₂, 1 ATP, and 2 CO₂.

Common Mistakes to Avoid

Plants only perform photosynthesis, not respiration.

Glycolysis requires oxygen.

CO₂ is released during glycolysis.

Memory Tips

Definition of cellular respiration

Two types of respiration: aerobic and anaerobic

Glycolysis occurs in cytosol, uses no oxygen

Glycolysis: Glucose → 2 Pyruvate + 2 ATP + 2 NADH
