Cellular Respiration (Glycolysis, Kreb’s Cycle, & Electron Transport Chain)

Cellular Respiration = the process of breaking down glucose into usable ATP, which powers many cell processes.

• Both eukaryotes & probaryotes do it

• Aerobic CR in eukaryotes has THREE parts

  
  C6H12O6 + 6O2 —> 6CO2 + 6H2O + ATP

  Where the Reactants Come From:

  Glucose (C6H12O6) is produced through Photosynthesis and transferred through the food chain to humans.

  Oxygen (60a) is produced as a byproduct of photosynthesis and breathed in through the atmosphere

  Step 1. GLYCOLYSIS

  PRODUCES:

  - NADH (~2)

  REQUIRES:

  • Glucose

  • Small amount of ATP

  • Step 2: KREB'S CYCLE (CHTic Acd Cycle)

  • Occurs in mitochondrial matrix

  • Aerobic (sort of)

  PRODUCES:

  • ATP (v2)

  • NADH (~G)

  - Occurs in the cytoplasm
  Anderabia process	Pyruvate - simpler
  - Doesn't require oxygen to occur	glucose molecules.
  - Requires ATe
  	NADH = a catalyst
  - pyruvate (~2)
  - ATP molecules (N4.)	used to prompt chemical reactions
  	in the body.
