Glycolysis and Glucogenesis: Q&A on Metabolic Pathways

Glycolysis and Glucogenesis: Q&A on Metabolic
Pathways




Glycolysis - ANSWERHydrolysis of glucose; major pathway for the utilization
of glucose



Cytoplasm - ANSWERWhere does anaerobic glycolysis occurs?



Lactate - ANSWERWhat is the end product of anaerobic glycolysis?



Mitochondria - ANSWERWhere does aerobic glycolysis occurs?



Pyruvate - ANSWERWhat is the end product of aerobic glycolysis?



Production of ATP - ANSWERImportance of glycolysis



1. Conversion of hexose to triose (Energy requiring stage)

2. Conversion of triose phosphate to pyruvate (Energy producing stage) -
ANSWER2 stage of glycolysis



Hexokinase (glucokinase) - ANSWERFirst enzymes in glycolysis: GLUCOSE-->
G6P



Glucose-6-Phosphate - ANSWERThe product of the first step of glycolysis

, Phosphoglucose isomerase - ANSWERConverts glucose 6-phosphate into
fructose 6-phosphate



Fructose-6-Phosphate - ANSWERStep 2: Glucose-6-phosphate------> ?



Phosphofructokinase - ANSWERThe enzyme that catalyzes the
phosphorylation of fructose-6-phosphate to form fructose-1-6-bisphosphate
in the third step of glycolysis.



Fructose-1,6-Bisphosphate - ANSWERStep 3: Fructose 6-phosphate --------> ?



To indicate that two phosphates are on different carbon atoms in fructose
and they are not connected to each other - ANSWERWhy is the term
"bisphosphate" is more appropriate to use?



Phosphofructokinase - ANSWERThe major regulatory enzyme of the glycolytic
pathway



Aldolase reaction - ANSWER4th step of Glycolysis.



Fructose 1,6 bisphosphate ---> Dihydroxyacetone phosphate +
Glyceraldehyde 3-Phosphate



Cleavage of the C6 carbohydrate backbone to 2 C3s.
