Glycolysis — Flashcards

A researcher is studying role of glucose metabolites in normal cellular function. -In the experiment generating ATP are measured. -In these cells, glycolysis of a single glucose molecule always yields pyruvate but sometimes generates no net ATP. -What cell is most likely being studied in this experiment?

45 y/o man comes with newly diagnosed diabetes mellitus. -A week ago comes with elevated fasting seum glucose level. -The physician recommends a medication that alters glucose metabolism within the liver by increasing the concentration of fructose 2,6-bisphosphate within hepatocytes. -What conversions will be inhibited by high intracellular concentrations of this metabolite?

The one to four glucose residues remaining on a branch after glycogen phosphorylase has shortened it are referred to as '_____''

Thiamine pyrophosphate (B1) is a cofactor for the enzyme _____ (glycolysis)

Conversion of glyceraldehyde-3P into 1,3-BPG (glycolysis) produces a molecule of _____

Anaerobic glycolysis produces a net of _____ ATP per glucose molecule

Conversion of phosphoenolpyruvate into pyruvate (glycolysis) produces a molecule of _____

What is the rate-limiting enzyme of glycolysis?_____

2-phosphoglycerate is converted into _____ via the enzyme enolase

The hallmark of what glycogen storage disease is a flat venous lactate curve with a rise in ammonia levels during exercise?_____
