Which of the following statements regarding the glycolysis pathway is FALSE? A) O Two pyruvate molecules are generated. B) O ATP molecules are generated via substrate-level phosphorylation C) O It does not require oxygen to operate D) O ATPS are used (hydrolyzed) in the beginning of glycolysis. E) O None of the above are false; they are all true statements

1)NADH is made from NAD+ by a)An oxidation-reduction reaction b)Oxidative phosphorylation c)A proton gradient d)A dehydration reaction e)Substrate-level phosphorylation 2. The energy used to make ATP via substrate-level phosphorylation is from a(n) a)Electron gradient b)Reduction reaction c)Phosphorylated molecule d)ADP molecule e) Protein gradient 3. Which of the following molecules, as written, is in its reduced form? a)NADH b)O2 c)NAD+ d)FAD e)CO2 4. Cellulose is a good structural molecule because a)The molecule is amphipathic, allow it to interact with water and nonpolar substances b)The bonds between the monomers are difficult to break, increasing its stability c)It is a mix of carbohydrate and protein, allowing it to form multiple types of bonds

Which of the following statements is correct? 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+ is oxidized by the action of hydrogenases. D) NAD+ can donate electrons for use in oxidative phosphorylation. E) NAD+ is reduced during fermentation in order for glycolysis to continue.
