Energy for the body
  • Trapped in chemical bonds of fats, proteins, and
    carbs (potential)
  • liberate energy
  • break bonds
  • release energy, CO2 and H20
  • Energy is transferred to ATP for use in the body

7
Glycolysis
  • Splitting sugar (glucose)
  • Used by all organisms
  • Occurs in cytoplasm
  • Phosphorylation
  • Adding a phosphate to a substance
  • NAD
  • Electron acceptor (carrier)
  • Used in electron transport chain for energy
  • nicotinamide adenine dinucleotide

8
Glycolysis
  • Animation
  • Smith College

9
Glycolysis
  • Where?
  • When?
  • Why?
  • Catabolic
  • Anabolic
  • What happens to pyruvate

10
Pyruvate
  • Aerobic - presence of oxygen
  • enters the Krebs cycle (mitochondrion)
  • tricarboxylic acid (TCA) cycle
  • Anaerobic - no oxygen
  • fermentation pathway
  • pyruvate forms lactic acid
  • Lactic acid is transported to liver to be
    converted
