2. Cellular respiration and ATP

  • Respiration occurs at two levels: body level and cellular level.
  • At body level, oxygen and carbon dioxide are exchanged between the body and the surroundings.
  • At cellular level, food is oxidized with or without oxygen.

3. Aerobic respiration: glycolysis, Krebs cycle, and electron transfer chain

  • In aerobic respiration, glucose is oxidized in three steps.
  • Glycolysis is the first step and occurs in the cytoplasm.
  • In glycolysis, one glucose molecule is broken down step by step to form pyruvic acid, ATP, NADH, and water.
