Especially Glycolysis Flashcards
what is the enzyme in step 1 of glycolysis?
hexokinase
what is the sugar in step 1 of glycolysis?
glucose
what happens in step 1 of glycolysis?
hexokinase spends an ATP so that glucose gets phosphorylated
what happens in step 2 of glycolysis?
glucose-6-phosphate gets converted to fructose-6-phosphate
what is the enzyme in step 2 of glycolysis?
phosphogluctose isomerase
what is the sugar in step 2 of glycolysis?
fructose-6-phosphate
what is the enzyme in step 3 of glycolysis?
phosphofructosekinase
what is the sugar in step 3 of glycolysis?
fructose-1,6-bisphosphate
what happens in step 3 of glycolysis?
Phosphofructokinase spends 1 ATP so that fructose-6-phosphate gets another phosphate
what happens in step 4 of glycolysis?
Aldolase breaks fructose-1,6-phosphate into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate
what is the sugar in step 4 of glycolysis?
fructose-1,6-bisphosphate
what are the enzyme in step 4 of glycolysis?
Aldolase
what happens in step 5 of glycolysis?
triose phosphate isomerase interconverts dihydroxyacetone phosphate and glyceraldehyde-3-phosphate
what happens in step 6 of glycolysis?
The Lord Giveth…
glyceraldehyde-3-phosphate dehydrogenase spends an NAD+ and an inorganic phosphate to simultaneously oxidize and phosphorylate glyceraldehyde-3-phosphate via REDOX rxn (so now it has 2 phosphates)
NADH comes out in the process
what is the enzyme in step 6 of glycolysis?
glyceraldehyde-3-phosphate dihydrogenase
what is the sugar as the end of step 6 of glycolysis?
1,3-biphosphaglycerate
what happens in step 7 of glycolysis?
The Lord taketh away…
Phosphoglyerate kinase removes one of the phosphates from 1,3-bisphosphoglyerate
Generates one ATP
what is the enzyme in step 7 of glycolysis?
Phosphoglycerate Kinase
what is the sugar at the end of step 7 of glycolysis?
3-phospyglycerate
what happens in step 8 of glycolysis?
phosphoglyeromutase moves 3-phosphoglycerate’s remaining phosphate from C3 to C2 (closer to its COO-)
what is the enzyme in step 8 of glycolysis?
phosphoglyeromutase
what is the sugar at the end of step 8 of glycolysis?
2-phosphoglycerate
what happens in step 9 of glycolysis?
enolase converts 2-phosphoglycerate to its high energy enol isomer
what is the enzyme in step 9 of glycolysis?
enolase
