glycolysis

• • doesnt require oxygen
• produces molecules with 3 carbons called pyruvate
• steps

  1. glucose
  2. hexose bisphosphate
  3. 2 tp molecules
  4. 2 pyruvate molecules
• • glucose is phosphorylated ( adds 2 phosphates)
  • hexose bisphosphate made (gets phosphate from 2 ATP molecules)
• • hexose bisphosphate splits into 2 TP molecules
• • each TP molecule turns into pyruvate and produces 2 ATP molecules
• overall yield of 2 ATP molecules per glucose
• overall yield of 4 ATP (each pyruvate makes 2 ATP molecules)
• • TP is oxidised in glycolysis (loses H)
  • Hydrogen transferred to NAD, makes NADH
• NAD is reduced
