in the case of 32 here's the calculation:

Glycolysis

Glycolysis give 2 NADH

if NADH enters through G3P shuttle it will yield 3 ATPs

so 2x3=

Each glucose gives two pyruvates

Each pyruvate entering TCA will give off

so 12x2 =

Adding

am sure you'll understand how malate shuttle gives 30 ATPs instead

I think level1 confusion stems from the fact that he forgot that each glucose gives two pyruvatesEach glucose gives two pyruvates

Always remember the glycolysis equation

Code:

`Glucose + 2Pi + 2ADP + 2NAD = 2 Pyruvate + 2ATP + 2NADH + 2H + 2H2O`

thats very cool but i think .. u all may forgot a step to convert pyruvate to Acetyl coA .. which yealds an Another mol. of NADH which add 3 ATP per pyruvate so Add 6 ATP per Gulcose which mean 1 Mol. of Glucose yealds

in the case of 32 here's the calculation:

Glycolysis2 ATPs/glucose

Glycolysis give 2 NADH

if NADH enters through G3P shuttle it will yield 3 ATPs

so 2x3=6 ATPs

Each glucose gives two pyruvates

Each pyruvate entering TCA will give off12ATPs

so 12x2 =24

Adding

24+6+2 = 32

am sure you'll understand how malate shuttle gives 30 ATPs instead

am i right ?!

You are absolutely rightthats very cool but i think .. u all may forgot a step to convert pyruvate to Acetyl coA .. which yealds an Another mol. of NADH which add 3 ATP per pyruvate so Add 6 ATP per Gulcose which mean 1 Mol. of Glucose yealds38 ATPper Glucose not 32 ATP

am i right ?!

i think malate shuttle produces 3 atp s as it uses nadh and G3P shuttle produces 2 as it uses FADH2

in the case of 32 here's the calculation:

Glycolysis2 ATPs/glucose

Glycolysis give 2 NADH

if NADH enters through G3P shuttle it will yield 3 ATPs

so 2x3=6 ATPs

Each glucose gives two pyruvates

Each pyruvate entering TCA will give off12ATPs

so 12x2 =24

Adding

24+6+2 = 32

am sure you'll understand how malate shuttle gives 30 ATPs instead

doesnt the g3p shuttle produce 1,5 mol atp a nadh-->fadh2 conversion?
