  1. The Aerobic System Cellular Respiration

  2. Goal: • I will be able to explain how my body converts food into a usable form of energy for my cells.

  3. Review • What are the two metabolic systems discussed previously and how do they provide energy?

  4. Cellular Respiration • Provides energy to sustain intense activity for long periods of time. Examples include biathlon, marathons, entire soccer game etc. • Process occurs in the mitochondria of cells and requires oxygen.

  5. Cellular Respiration • The overall equation for cellular respiration is: C6H12O6 + 6O2 +36ADP +36P → 6CO2 + 36ATP +6H2O

  6. Cellular Respiration • Glycolysis occurs in the cytoplasm and creates two pyruvate molecules. • Pyruvate molecules move into the mitochondria and are converted into acetyl CoArather than lactic acid. • The acetyl CoA molecules move into the citric acid cycle (Krebs cycle). Through a series of eight reactions, two ATP molecules as well as “high energy storing” molecules are produced. • The final stage is called the Electron Transport Chain.

  7. Electron Transport Chain • This stage occurs in the matrix of the mitochondria. • Electrons are removed from the “high energy storing” molecules produced in the citric acid cycle which results in free energy that is used to attach a phosphate group to ADP creating ATP. • There are 36 ATP molecules produced by the end of cellular respiration (citric acid cycle + electron transport chain).
