ELECTRON TRANSPORT

Net Reaction:

NADH = 3 ATP

FADH2 = 2 ATP

Aerobic= Requires O2, mitochondria

NADH from glycolysis??

 

NET REACTION - OVERALL

Glucose ® 6 CO2 + 2 ATP + 2 GTP + 2 NADH + 8 NADH +2 FADH2

= 36 moles of ATP

1 mole of ATP = 7.3 kcal Þ 36 X 7.3 = 263 kcal (trapped energy)

1 mole glucose (180g):

3.75 kcal/g Þ 180 X 3.75 = 675 kcal (gross energy)

 Efficiency??

(263 realized / 675 potential) X 100 = 39%

Rest of the energy??

Lost as heat!
