Arrange the balanced biochemical equations for all the reactions in the catabolism of glucose to two molecules of glyceraldehyde 3-phosphate (the preparatory phase of glycolysis). First step Last step Answer Bank Fructose 1,6-bisphosphate- dihydroxyacetone phosphate + glyceraldehyde 3-phosphate Fructose 6-phosphate + ATP → fructose 1,6-bisphosphate + ADP Glucose + ATP glucose 6-phosphate + ADP Dihydroxyacetone phosphate glyceraldehyde 3-phosphate Glucose 6-phosphate →→→ fructose 6-phosphate

Please help fill out the metabolic Pathway table of Gluconeogenesis and Tricarboxylic by listing its enzymes and functions

Indicate what will happen (increase, decrease or no effect) to the activity of the enzyme or rate of the metabolic pathway given the following conditions.

Hexokinase phosphohexose isomerase [Choose ] [Choose ] Is not the trapping reaction catalyzes an ATP-dependent phosphorylation of its substrate. Is irreversible and carries out substrate-level phosphorylation. PFK-1 aldolase triose-phosphate isomerase Splits the carbohydrate in two. Product is 2-phosphoglycerate. Is reversible and carries out substrate-level phosphorylation. Product is fructose-6-phosphate. Catalyzes the trapping reaction Makes a 2nd mole of G3P from DHAP Produces a high-free energy compound but no NADH or ATP. Oxidizes an aldehyde. GAPDH [Choose ] Phosphoglycerate kinase [Choose ]

Allosteric regulation plays a very important role in the regulation of glycogen metabolism. Which of thefollowing is correct? -AMP allosterically inhibits glycogen phosphorylase -Glucose-6-phosphate allosterically activates glycogen synthase -Both A and B -Neither A nor B   The value of standard free energy change for reaction A --> B is +3.7 kJ/mol. Under which of thefollowing conditions, the reaction will most likely become exergonic in the direction as written? -Mass action ratio is larger than the equilibrium constant -Couple with ATP hydrolysis -Both A and B -Neither A nor B
