Which of the following is a common feature of the processes indicated by both letters D and E?
a. movement of organic food molecules between catabolic pathways
b. movement of phosphate groups associated with ADP
c. movement of hydrogen atoms associated with NADH
d. movement of pyruvic acid into the mitochondria
c. movement of hydrogen atoms associated with NADH
The hydrogen atoms removed from food molecules during glycolysis and the citric acid cycle can be thought of as the combination of protons and highenergy electrons. These are both carried by the coenzyme NADH (and, in the case of the citric acid cycle, FADH2) from the catabolic pathways to the electron transport chain.
