Do expect the cell to produce more ATP from one glucose molecule or from one fatty acid molecule? Explain your answer. Indicate whether the following statements are true or false. If a statement is false, explain why it is false The proteins of the electron-transport chain remove a pair of high-energy electrons from the cofactors, NADH and FADH_2, after which the electrons move across the inner mitochondrial membrane to maintain the voltage gradient. Gluconeogenesis is a linear reaction pathway that...

Louis Pasteur observed that when oxygen is introduced to cells consuming glucose at a high rate in an anaerobic environment, fermentation ceases and the rate of glucose consumption decreases. This phenomenon is called the Pasteur effect. The basis of this effect is the shift from fermentation to oxidative phosphorylation to regenerate NAD*. Additionally, the cells also synthesize ATP through oxidative phosphorylation. In respiration-deficient yeast mutants that lack cytochrome oxidase, the Pasteur effect is not seen. Select the reasons why the...

7) Why do hydrolysis reactions occur more readily in solution than dehydration reactions? A) Hydrolysis reactions increase G, or Gibbs free energy of the system, B) Hydrolysis reactions are endergonic and increase entropy of the system. C) Hydrolysis reactions are exergonic and decrease entropy of the system. D) Hydrolysis reactions are exergonic and increase entropy of the system. 8) How do cells use the ATP cycle illustrated in the figure? AAA W A) Cells use the cycle to recycle ADP...

Ignore question 4.
1. Calculate the number of ATP produced per carbon atom for a molecule of glucose under oxidative phosphorylation (remember we use as a rule of thumb 2.5ATP per NADH and 1.5ATP per FADH2 based on the number of protons pumped in the ETC). 2. Calculate the number of ATP produced per carbon atom for a saturated fatty acid between 12 and 18 carbons long (make sure you clearly indicate the length of fatty acid you choose, e.g...

4. Trace the fate of hydrogens removed from glucose during glycolysis when oxygen is present in muscle cells; compare this to the fate of hydrogens removed from glucose when the amount of available oxygen is insufficient to support aerobic respiration. 5. Why is each of the following essential to chemiosmotic ATP synthesis? (a) electron transport chain (b) proton gradient (c) ATP synthase complex? 6. Sum up how much energy (as ATP) is made available to the cell from a single...
