• outline the differences in the 2 ways by which ATP is produced in respiration

  1. substrate level phosphorylation - ADP + Pi make ATP
  2. oxidative phosphorylation

  ATP SYNTHAHSE (from op)

  • hydrogen lost from nadh/fadh (dehydrogenation)
  • Must be PROTON GRADIEN to continue the process of 3H+ ENTERING THE COMPLEX TO MAKE ATP
  • electrons go down the ETC
• Describe the production of ATP by substrate level phosphorylation in different stages of respiration with reference to no. of ATP mol. made


  • 4 ATP made in glycolysis but 2 ATP used from Glycolysis
  • 2 ATP molecules per glucose from glycolysis
  • when triose (bi) phosphate broken down to pyruvate
  • 1 ATP made per turn of the Krebs
  • 5 carbon compound converted to 4 carbon compound OAA
