Study Set Content:
The second step of glycolysis involves the conversion of glucose-6-phosphate to
fructose-6-phosphate (F6P)
As the name of the enzyme suggests, this reaction involves an
isomerization reaction
Step 3: enzyme involved
Phosphofructokinase
In the third step of glycolysis, fructose-6-phosphate is converted to
fructose- 1,6-bisphosphate (FBP)
Similar to the reaction that occurs in step 1 of glycolysis, a (blank) provides the phosphate group that is added on to the F6P molecule
a second molecule of ATP
Step 4: Enzyme
Aldolase
Aldolase splits fructose 1, 6- bisphosphate (FBP) into
two sugars that are isomers of each other
2 sugars in aldolase
dihydroxyacetone phosphate and Glyceraldehyde-3-phosphate
Step 5: enzyme involved
Triosephosphate isomerase
The enzyme triosephosphate isomerase rapidly inter- converts the molecules
dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (GAP).
Step 6: enzyme involved
Glyceraldehyde-3- phosphate Dehydrogenase
what does it do Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)
dehydrogenates
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) dehydrogenates and adds an
inorganic phosphate
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) dehydrogenates and adds an inorganic phosphate to
glyceraldehyde 3-phosphate
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) dehydrogenates and adds an inorganic phosphate to glyceraldehyde 3-phosphate, producing
1,3- bisphoglycerate.
Step 7 enzyme involved
Phosphoglycerate kinase
In this step, 1,3 bisphoglycerate is converted to
3- phosphoglycerate
This reaction involves the loss of a (blank) from the starting material
phosphate group
The phosphate is transferred to a molecule of
ADP
The phosphate is transferred to a molecule of ADP that yields our
first molecule of ATP
