A) Phosphoglycerate mutase E) Pyruvate kinase B) Aldolase F) Phosphofructokinase-1 C) Phosphoglycerate kinase G) Hexokinase D) Glyceraldehyde-3-phosphate dehydrogenase 5. Blood Lactate Levels during Vigorous Exercise The following graph shows the concentrations of lactate in blood plasma before, during, and after a 400 m sprint. Use your knowledge from chapter 14 to explain the causes of the rapid rise in lactate concentration? --Before-- - After Blood...
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...

6. In question 5, what is the most important reaction involved in formation of lactate? A) dihydroxyacetone phosphate glycerol 3-phosphate D) pyruvate → lactate B) oxaloacetate → malate E) isocitrate → a-ketoglutarate C) glucose 6-phosphate → fructose 6-phosphate 7. During the process in question 5 (the rapid rise in lactate concentration), the NADH must be reoxidized to NAD+. Which of the following enzymes will be most affected if NADH is not reoxidized? A) Pyruvate kinase. C) Phosphofructokinase-1. E) aldolase. B)...
Need help with this. I need to match the text box with the following hexokinase,aldolase,phosphofructokinase,enolase,aconitase,furmarase. Thanks 10 pts Question 22 These enzymes are involved in Glycolysis and the Citric Acid cycle. Match the term with the correct function. Only one function is listed for each enzyme. Hexokinase [Choose Choose l Converts Citrate to isocitrate in 2 steps Succinate Dehydrogenase Aldolase Makes 2 three carbon molecules from Fructose 1.6 biphosphate Phosphorylates Fructose 6-phosphate in the presence of ATP Form Glucose 6....
Pyruvate dehydrogenase and glyceraldehyde 3 phosphate dehydrogenase use NAD as an electron acceptor, why don't the two enzymes compete for the same pool of cellular NAD?
In the Calvin Cycle, for each molecule of glyceraldehyde 3-phosphate produced, how many ATP and NADPH are required in C3 plants? How many in C4 plants?
