Problem 1: Standard ATP Calculation

Q: Calculate the total ATP yield from complete aerobic oxidation of one glucose molecule. Show all stages.

Solution:

Stage	Direct ATP	NADH produced	$FADH_{2}$ produced	GTP
Glycolysis	2 ATP net	2 NADH	0	0
Oxidative decarboxylation	0	2 NADH	0	0
TCA cycle (×2 turns)	0	6 NADH	2 $FADH_{2}$	2 GTP
Totals	2	10 NADH	2 $FADH_{2}$	2

ETS conversion: 10 NADH × 3 ATP = 30 ATP; 2 $FADH_{2}$ × 2 ATP = 4 ATP Direct ATP: 2 (glycolysis) + 2 (GTP equivalents) = 4 ATP Grand Total = 30 + 4 + 4 = 38 ATP
