Concept explainers
(a)
Interpretation:
The way in which the conversion of pyruvate to lactate is similar to pyruvate to ethanol conversion needs to be explained.
Concept introduction:
The oxidation of glyceraldehyde 3-phosphate generates NADH resulting net oxidation in the glucose to pyruvate conversion. The oxidation-reduction does not take place in the glucose to lactate conversion. The transfer of electrons from NADH to pyruvate is catalyzed by lactate dehydrogenase to from lactate.
(b)
The ways in which two processes are different needs to be explained.
Concept introduction:
The oxidation of glyceraldehyde 3-phosphate generates NADH resulting net oxidation in the glucose to pyruvate conversion. The oxidation-reduction does not take place in the glucose to lactate conversion. The transfer of electrons from NADH to pyruvate is catalyzed by lactate dehydrogenase to from lactate.

- Identify the following intermediate in the citric acid cycle, and tell whether it has R or S stereochemistry:arrow_forwardWhy are two equivalents of NADPH required to reduce ydroxymethylglutaryl-CoA to mevalonic acid?arrow_forwardExplain why the conversion of pyruvate to lactate is a reversible reaction but the conversion of pyruvate to acetaldehyde is not reversiblearrow_forward
- What factors influence the metabolic rate of citrate in the mitochondria? What is the fate of cytosolic pyruvate when it is reduced by cytosolic NADH? Could leptin be used to treat obesity?arrow_forwardwhat reaction is catalyzed by phosphoglucomutase(subtrates and products)? What is the cofactor for this reaction?arrow_forwardIn glycerol metabolism, the oxidation of sn-glycerol 3-phosphate to give dihydroxyacetone phosphate is catalyzed by sn-glycerol-3-phosphate dehydrogenase, with NAD+ as cofactor. The reaction is stereospecific, occurring exclusively on the Re face of the nicotinamide ring.arrow_forward
- draw the chemical structures of the reactant and product of the following reactions: a.) addition of a phosphate group to (ex: phosphorylation of) glycose b.) addition of a phosphate group to (ex: phosphorylation of) fructose-6-phosphate c.) addition of a phosphate group to (ex: phosphorylation of) phosphoenolpyruvatearrow_forward4.What is the heme oxidation state in cytochrome c following treatment with sodium ascorbate??arrow_forward(a) Which intermediate(s) in the citric acid cycle contain one chirality center? (b) Which intermediate(s) contain a 3 °alcohol?arrow_forward
- Which intermediate(s) in the citric acid cycle contain one chirality center? Which intermediate(s) contain a tertiary alcohol?arrow_forwardCells can also convert a-keto acids into amino acids, but because the reagents organic chemists use for this reaction are not available in cells, they carry out this reaction by a different mechanism. a. What amino acid is obtained from the reductive amination of each of the following metabolic intermediates in a cell by reductive amination? b. What amino acids are obtained from the same metabolic intermediates when the amino acids are synthesized in the laboratory?arrow_forwardDraw the reaction then identify the reaction mechanism that took place, SN1, SN2 and etc. Metabolic pathway: Conversion of Pyruvate to Acetyl CoA Citric acid cycle Gluconeogensis pathway (pyruvate to glucose)arrow_forward
