3.3.9

Describe the production of ATP from glucose and fatty acids by the aerobic system.

In the presence of oxygen, pyruvate is processed by the Krebs cycle, which liberates electrons that are passed through the electron transport chain producing energy (APT).

Fats are also broken down by beta-oxidation that liberates a greater number of electrons thus more ATP. In the presence of oxygen and in extreme cases protein is also utilized.
Acetyl-CoA

    1. Glycogen is converted into Glucose (glycolysis).
      - Low levels of phosphocreatine and increased levels of calcium activates phosphofructokinase (PFK).PFK assists in the breakdown of glucose into pyruvic acid.
      - A presence in oxygen converts pyruvic acid into Acetyl coenzyme A (CoA) in the mitochondria.
      - Krebs Cycle:
      - Electron Transport chain:
      - The hydrogen is carried into the Electron Transport chain in the Cristae within the mitochondria
      - Hydrogen splits into a Hydrogen ion and an electron.
      - Hydrogen ion oxidizes to form water.
      - Electrons provide energy to resynthesize ATP.
      - This process forming 34 molecules of ATP
