Glycolysis Flashcards
The enzyme that accomplishes pyruvate oxidation is a membrane associated complex. TF
True
Which compound is an allosteric regulator of both a kinase and a phosphorylase?
NAD+
Glycolysis prepares for the pathways where ATP is produced but doesn’t make ATP itself. TF
False: is produced in stage 3
Glycolysis involves the following reactions: A kinase reaction creating a sugar phosphate. TF
True
The committed step reaction of glycolysis is not reversible for gluconeogenesis. TF
True
List the intermediates of glycolysis
Phosphoglycerate
Glyceraldehyde-3-phosphate
Biphosphoglycerate
Phophoenolpyruvate
(NOT glycerol-3-phosphate)
Which compound is part of the gluconeogenesis but not glycolysis?
Oxaloacetate
Glycolysis is the pathway for metabolizing the preferred macronutrient fuel.TF
True
Glycolysis includes investing NADH. TF
False: Produces NADH
Glycolysis involves splitting a six carbon sugar into two three carbon sugars. TF
TRue
Glycolysis includes harvesting ATP’s directly, TF
True
The regulation of glycolysis is a pathway with a committed step that is allosterically regulated. TF
True: allosteric binding of NAD+
Glyceraldehyde-3-phosphate and dihydroxyacetone phosphate are metabolically __________.
Interconvertible
There is and extra intermediate in gluconeogenesis that glycolysis doesn’t have. TF
True
________ is required in order to run glycolysis and can be provided by fermentation in cells that can metabolize anaerobically.
Glucose?
GLycolysis is the pathway for metabolizing the preferred macronutrient fuel of most cells. TF
True
Glycolysis involves of the following reactions: An oxidation releasing carbon dioxide. TF
False: releases lactate or ethanol
The enzyme that accomplishes pyruvate oxidation is allosterically regulated. TF
True: PFK enzyme
In cells that can do fermentation, why would they do fermentation?
Anaerobic (conditions)
Which of of the following compounds is an allosteric regulator of both a kinase and a phosphorylase?
Fructose-2,6-biphosphate: ««_space;quantity in the cell decides if the cell is going to perform glycolysis or gluconeogenesis. This is acheived by binding FBP-1 (a phosphorylase) and PFK-1(a kinase).
