08 HMP Shunt


  • offshoot of glycolysis

Pathway

  • not in mitochondria
  • oxidative: G6P to R5P
  • reductive: R5P to F6P and G6P

Oxidative

  • CO2 removed to go from 6C to 5C

Reductive

R5P

NADPH

  • NADH very different function from NADPH
  • not used to generate ATP

  • donate electron to other molecules, reducing them

Phagocytosis

  • uses NADPH from HMP shunt

Oxidative Damage Protection

  • glutathione protects RBC from oxidative damage

  • bite cells: spleen try to remove heinz bodies
