What similar role do coenzyme \(\mathrm{Q}\) and cytochrome c serve in the electron transport chain?

When myristic acid (a saturated fatty acid with 14 carbon atoms) is completely oxidized by \(\beta\) -oxidation, how many molecules of each are formed? a. acetyl-CoA b. FADH \(_{2}\) c. NADH

What coenzyme is needed as an oxidizing agent in glycolysis?

When stearic acid (a saturated fatty acid with 18 carbon atoms) is completely oxidized by \(\beta\) -oxidation, how many molecules of each are formed? a. acetyl-CoA b. FADH \(_{2}\) c. NADH

If the carbonyl carbon atom of acetyl-CoA is labeled, where does the label appear after the acetyl-CoA goes through one round of the citric acid cycle?

Calculate a. the total number of molecules of ATP produced for each molecule of glucose converted to pyruvate in glycolysis. b. the number of molecules of ATP hydrolyzed in phase I of glycolysis. c. the net ATP production from glycolysis alone.

What is the electron acceptor at the end of the electron transport chain? To what product is this compound reduced?

What are the expected products from the enzymatic action of chymotrypsin on each amino acid segment? a. gly-ala-phe-thr-leu b. ala-ile-tyr-ser-arg c. val-trp-arg-leu-cys

The average adult consumes about 65 g of fructose daily (either as the free sugar or from the breakdown of sucrose). In the liver, fructose is first phosphorylated to fructose 1 -phosphate, which is then split into dihydroxyacetone phosphate and glyceraldehyde. Glyceraldehyde is then phosphorylated to glyceraldehyde 3-phosphate, with ATP as the phosphate group donor. Write the equations (using structural formulas) for these three steps. Indicate the type of enzyme that catalyzes each step.

How is the NADH produced in glycolysis reoxidized when oxygen supplies are limited in a. muscle cells? b. yeast?
