A) NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle. B) NAD+ has more chemical energy than NADH. C) NAD+ can donate electrons for use in oxidative phosphorylation. D) In the absence of NAD+, glycolysis can still function. E) NAD+ is the final electron acceptor in electron transport chain. 12. Most CO2 from respiration is released during A) glycolysis. B) the citric acid cycle. C) Pyruvate breakdown D) electron transport. 13. Which one of the following is formed by the removal of a carbon (as CO2) from a molecule of pyruvate? A) ATP B) acetyl COA C) citrate D) water

Answer 1

10. A) Anabolic pathways create complex molecules using the energy from catabolic pathways.

Catabolic pathway release energy by oxidation of the complex molecule and store the energy in the form of high energy molecule ATP. Then at the time of the anabolic pathway, the energy of the ATP is used to form complex molecules from the smaller units.

For example, glucose is broken down by glycolysis and Kreb's cycle and produce ATP and the ATP produced will be utilized for glycogen synthesis and fatty acid biosynthesis from smaller subunits glucose and acetyl-CoA.
