Which of the following statements about glycolysis is FALSE? O It generates 2 molecules of ATP net per molecule of glucose. O It is located in the cytosol of both prokaryotes and eukaryotes. O It requires an input of 2 molecules of ATP per molecule of glucose to generate fructose-1,6-bisphosphate. O It generates 2 molecules of NADH per molecule of glucose. O It liberates 2 molecules of CO2 per molecule of glucose.
Regarding pathways that feed glycolysis, which of the following statements is false? Mannose is also a substrate of hexokinase. Galactose requires UDP-glucose in its conversion to fructose-6-phosphate. Fructose is phosphorylated by hexokinase in muscle cells. Glucose-6-phosphatase is part of the pathway that breaks down glycogen in muscle cells.
Which of the following statements concerning oxidative phosphorylation is false? Group of answer choices: The electron transport chain generates an electrochemical gradient that drives the production of ATP. ATP synthase with fewer subunits in its c ring will produce more ATP per proton. A “loose” β subunit of ATP synthase becomes a “tight” site as it produces ATP. When the supply of NADH and QH2 (ubiquinol) decreases, ATP synthase produces more ATP.

State which steps of the cellular respiration pathway lead to the generation of the energy molecules. State the TOTAL number of ATP molecules the ONE of these converted alpha-ketoglutarate molecules can produce and explain how all the ATP molecules are generated.
