Gluconeogenesis Pathway Assignment for you to review/study gluconeogenesis. Gluconeogenesis Pathway Assignment – • Write the reactions starting from two molecules of alanine to a molecule of glucose. • Include reactants and products (names and structures) • Cofactors, coenzymes, cosubstrates (do not need structures of the cofactors, coenzymes, etc.) • Enzyme names • Overall reaction of the pathway - remember you are starting with two alanine.
Draw the metabolic pathway from diazepam to oxazepam. Include the molecular structures and the necessary enzymes to catalyze the reactions. Highlight or circle the functionality that is changing in each step.
Correctly match the following enzymes with the metabolic pathway they regulate. __ Phosphoenolpyruvate carboxykinase a. Gluconeogenesis __ Pyrubate dehydrogenase complex b. Glycolysis __ Glycogen Synthase c. Citric Acid Cylcle (Krebs) __ Pyruvate Carboxylase d. Glycogenolysis __ Pyruvate Kinase e. Glycogenesis
Which pair of opposite enzymes in the glycolysis and gluconeogenesis pathway are not allosterically regulated but rather regulated by compartmentalization? Select one: a. pyruvate kinase/PEP carboxykinase b. phosphofructokinase 1/fructose-1,6-bisphosphatase c. phosphofructokinase 2/fructose-2,6-bisphosphatase d. hexokinase/glucose-6-phosphatase
1. Bypassing the pyruvate kinase reaction. Gluconeogenesis and glycolysis are opposing pathways that share seven enzymes. The exergonic steps in glycolysis cannot be simply reversed because that would be too energetically costly. Thus, these steps are "bypassed" in gluconeogenesis with a separate set of enzymes. a. Explain why the reaction catalyzed by pyruvate kinase is energetically favorable and essentially irreversible in the cells. b.Explain how the cells that run gluconeogenesis are able to bypass this step with specific reactions that...
Which of the following is true about gluconeogenesis? The pathways uses all the same enzymes as glycolysis. Oxaloacetate is diverted from citric acid cycle to make glucose It is a pathway that is promoted with insulin secretion It role is to provide ketone bodies for export to other tissues when other sources of glucose are exhausted.
What is not true about gluconeogenesis? Select one: a. Gluconeogenesis shares seven steps of glycolysis b. Three irreversible steps that differ between gluconeogenesis and glycolysis are far from equilibrium. c. Forming one glucose from pyruvate produces 4 ATP, 2 GTP and 2NADH d. Acetyl-CoA can be converted into glucose in plants and microbes, but not mammals. e. Gluconeogenesis and glycolysis are reciprocally regulated to prevent wasteful operation of both pathways at the same time. D and B are wrong answers...
1. X10 PTS) Draw the pathway for de novo CTP biosynthesis. Show the structures and names of all reactants and products, as well as the names of the enzymes. You do not need to draw the structures of ATP, NAD+, CoA, etc., but do show them as reactants or products in the appropriate places. You do not need to show the mechanisms of the enzymes.
