1. You have given all the enzymes and intermediates in glycolysis. Choose the right enzymes and intermediates and draw the glycolytic pathway. Decorate the diagram by adding ATP, ADP, H", NADH, NAD', P, and H20 where necessary. All the steps are reversible except 1, 3 and 10; draw appropriate arrow. First arrange the reactants in the correct order. Reactants/intermediates: 3-phosphoglycerate glucose Phosphoenolpyruvate dihydroxyacetone phosphate Pyruvate glucose 6-phosphate 1,3-bisphosphoglycerate fructose 6-phosophate 2-phosphoglycerate glyceraldehyde 3-phosphate fructose 1,6-bisphosphate Enzymes: Phosphoglucoisomerase phosphoglycerate kinase phosphoglycerate...

Question 3 Glucose labeled with 14C in C-3 and C-4 is completely converted to acetyl-CoA via glycolysis and the pyruvate dehydrogenase complex. What percentage of the acetyl-CoA molecules formed will be labeled with 14C, and in which position of the acetyl moiety will the 14C label be found? Select the correct answer and explain your reasoning 100% of the acetyl-CoA will be labeled at C-1 (carboxyl). 100% of the acetyl-CoA will be labeled at C-2. 50% of the acetyl-CoA will...

Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...

3. You are given 90 mg of the following radioactively labeled carbohydrate, which contains a total of 3 uCi of 14C (14C = *). Draw the specific degradation pathway required to metabolize this molecule into a 3-Carbon subunit (pyruvate). Noting in this pathway we also incubated with a triose phosphate isomerase inhibitor (assume 100% inhibition). Specifically label the radioactive position(s) in the final product(s) and account for all radioactivity observed as this starting compound progresses through the pathway. Finally, calculate...

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...
