Fructose , after being absrobed ,goes through two pathways. Either it forms fructose-6-phosphate (by hexokinase) or it gets phosphorylated to fructose-1-phosphate by fructokinase found in liver.since liver contains much of he fructose obtained from diet fructose-1-phosphate is produced in appreciable amounts. Fructose-1-phosphate is acted upun by ALDOLASE B which breaks it into glecraldehyde and Dihydroxyacetone phosphate. both these enter glycolysis and since reactions catalyzed be hexokinase and epecially PFK-1 have been skipped in Fructose-1-phosphate metabolism hence glycolysis occurs faster ( PFK1 reaction is the main rate limiting step in glycolysis)

Which steps in glycolysis are irreversible?
The steps in glycolysis that are irreversible are the generation of fructose-6-phosphate from fructose-1,6 bisphosphate. All other steps of glycolysis are reversible.
Why only glucose enters into glycolysis why not other sugars directly enter into glycolysis?
Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.
What is the intermediate product of glycolysis that can be used in the biosynthesis of lipids?
The intermediate products of glycolysis include glucose-6-phosphate, fructose-6-phosphate, fructose-1 6-bisphosphate, PGAL, bisphosphoglycerate, and PEP. The main intermediate products are fructose-1 6-bisphosphate, PGAL, and PEP.
How can you use the word infusion in a sentence?
We watched them while they were in the middle of the infusion.
What is the Difference between bolus injection and bolus infusion?
The difference between injection and infusion is the injection is completed with a syringe. The infusion is accomplished through an IV.
Which steps in glycolysis are irreversible?
The steps in glycolysis that are irreversible are the generation of fructose-6-phosphate from fructose-1,6 bisphosphate. All other steps of glycolysis are reversible.
Rapid potassium infusion causes diastolic or systolic cardiac arrest?
Rapid potassium infusion causes diastolic and not systolic cardiac arrest.
Glycolysis involves producing energy from carbohydrates. Often times, our foods don't have just glucose, but other sugars such as fructose (in table sugar) and galactose (in milk). Let's consider fructose?
Fructose-6-phosphate
Enzymes used in glycolysis?
glucose, fructose, glyceraldehyde
Which is the committed step of glycolysis?
The committed step of glycolysis is the reaction catalyzed by phophofructokine (PFK) converting fructose-6-phosphate into fructose-1,6- bisphosphate. The reaction is irreversible and secondly, it's the only reaction peculiar to the glycolysis.
What is the role of phosphofructokinase-2 in glycolysis?
Phosphofructokinase-2 converts fructose-6-phosphate to fructose-2,6-bisphosphate.
3rd reaction of glycolysis. reactants, products, enzymes, reversibility?
Fructose-6-phosphate to fructose 1,6-bisphosphate. Phosphofructokinase (PFK). Requires ATP, Mg. First majorly regulated step of glycolysis. Irreversible
Why only glucose enters into glycolysis why not other sugars directly enter into glycolysis?
Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.
Raw materials needed for glycolysis?
Glycolysis is inherent in the process of respiration. The cell requires glucose and oxygen during glycolysis and water is the by-product
How does fructose get metabolized by the body?
Possible Answers: I, II, and III
What is the intermediate product of glycolysis that can be used in the biosynthesis of lipids?
The intermediate products of glycolysis include glucose-6-phosphate, fructose-6-phosphate, fructose-1 6-bisphosphate, PGAL, bisphosphoglycerate, and PEP. The main intermediate products are fructose-1 6-bisphosphate, PGAL, and PEP.
The second step of glycolysis involves the conversion of ______ into?
glucose-6-phosphate . . . fructose-6-phosphate
