Q

Priming reactions

A
  • Two high energy phosphates from 2 ATP molecules are added to 6 carbon molecule glucose
  • produces 6 carbon molecule with 2 phosphates

Q

Cleavage

A
  • 6 carbon molecule with 2 phosphates is split in 2

- forms 2 3-carbon sugar phosphates

Q

Oxidation

A
  • additional inorganic phosphate incorporated into each 3 carbon phosphate
  • oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
  • oxidation reactions also yield NADH

Q

ATP formation

A
  • oxidation reaction converts the 2 sugar phosphates into intermediates that can transfer a phosphate to ADP to from ATP
  • net energy yield of 2 ATP and 2 NADH
