15. Production of NADH by glycolysis requires an input of the oxidized molecule NAD+. Where does this supply of NAD+ come from in the absence of oxygen?

It is regenerated by reducing pyruvate to ethanol or lactic acid.

16. Glycolysis results in the partial oxidation of glucose to pyruvate. This means that

In the process of the conversion of glucose to pyruvate, some potential energy is transferred to NADH and ATP

17. The breakdown of one glucose molecule during glycolysis results in two molecules of pyruvate, each of which is then oxidized to a molecule of acetyl-CoA, and these, in turn, are substrates for the citric acid (Krebs) cycle. If all three fatty acids of a triacylglycerol molecule (a fat molecule) are myristic acid (C14, having 14 carbons), how many acetyl-CoA molecules would result from beta-oxidation of the molecule?

18. The light reactions of photosynthesis take place in the _____ of prokaryotes

thylakoids

19. In aerobic cellular respiration, the role of oxygen gas (O2) is to _______.

accept electrons to produce water

20. The large amount of O2 in the atmosphere enables life on Earth. We know that photosynthetic organisms (cyanobacteria) are responsible for the high levels of atmospheric O2. Why is this so?

Because photosynthetic organisms produce O2 and consume CO2-

21. In the light-dependent reactions of photosynthesis, light energy is converted to chemical energy stored in:

ATP and NADPH
