Glycolysis2 Flashcards
What enzyme cleaves off the fructose 1,6-bisphosphate molecule?
Aldolase
What enzyme converts the Dihydroxyacetone phosphate molecule to G3P?
Triose-Phosphate isomerase
What enzyme dehydrogenates the G3P molecule?
Glyceraldehyde 3 phosphate dehydrogenase
At what step of glycolysis does the first substrate level ATP forms?
7th step from the conversion of 1,3BPG by PG kinase
What happens at the 8th step of glycolysis?
Phosphoglycerate Mutase converts the 3-PG to 2-PG (This is not isomerization)
What is the Function of enolase enzyme in the glycolysis process?
It dehydrogenates the 2-PG to phosphoenolpyruvate molecule
At what step does the second substrate level ATP phosphorylation takes place?
At the 10th step during conversion of PP to pyruvate
At what steps of glycolysis are ATP used?
1st and 3rd
Why does the G6P to F6P isomerization happens?
Due to presence of carbonyl compound on the 1st carbon of glucose. Aldose converted to Ketose compound
What are the irreversible reactions of glycolysis?
All are reversible except the 1st, 3rd and 10th steps
What are the two phases of glycolysis?
Preparatory and payoff phases
How many ATPs are produced and used in glycolysis?
4ATPS are produced whereas 2ATPs are consumed hence net ATP produced is 2
What is the NAD+ reducing stage of glycolysis?
6th step when G3P is being converted to 1,3-BPG
How many NADHs are produced at glycolysis level?
2
At what stage is water produced in glycolysis?
During conversion of 2-PG to Phosphoenolpyruvate
