Question
The three boxes in this diagram represent the three major biosynthetic pathways in aerobic net reactant or products
Arrows numbered 4, 8 and 12 can all be
-
NADH
-
ATP
-
H2O
-
FAD+ Or FADH2
Solution
B.
ATP
Pathway A is glycolysis, pathway B is the kerb' cycle and pathway C is oxidative phosphorylation
Arrow 1 - ADP or NAD+
Arrow 2 - Pyruvate
Arrow 3 - NADH
Arrow 4 - ATP
Arrow 5 - ADP, NAD+ or FAD
Arrow 6 and 7 - FADH2 and NADH (either one can be 6 or 7)
Arrow 8 - ATP or CO2
Arrow 9 and 10 - O2 and ADP (either one can be 9 or 10)
Arrow 11 and 12 - H20 and ATP (either one can be 11 or 12)
Arrow 6 and 7 - FADH2 and NADH (either one can be 6 or 7)
Arrow 8 - ATP or CO2
Arrow 9 and 10 - O2 and ADP (either one can be 9 or 10)
Arrow 11 and 12 - H20 and ATP (either one can be 11 or 12)
