Glycolysis Flashcards
Glycolysis Step 1:
Input
Enzyme
Output
Byproduct
Hexokinase converts glucose to glucose 6-phosphate and ATP is used and converted to ADP
Glycolysis Step 2:
Input
Enzyme
Output
Byproduct
Phosphoglucoisomerarse converts glucose 6-phosphate into fructose 6-phosphate
Glycolysis Step 3:
Input
Enzyme
Output
Byproduct
Phosphofructokinase converts fructose 6-phosphate to fructose 1,6-bisphosphate by using one ATP and converting it to ADP
Glycolysis Step 4 & 5:
Input
Enzyme
Output
Byproduct
Aldolase converts fructose 1,6-bisphosphate into TWO glyceraldehyde 3-phosphate (G3P) and dehydroxyacetone phosphate DHAP (step 4) which can be converted to glyceraldehyde 3-phosphate (G3P) by Triosephosphate isomerase (step 5)
Glycolysis Step 6:
Input
Enzyme
Output
Byproduct
3 phosphate dehydrogenase converts (2) glyceraldehyde 3-phosphate (G3P) into (2) 1,3 bisphosphoglycerate by converting 2NAD+ to 2NADH and releasing 2 H+
Glycolysis Step 7:
Input
Enzyme
Output
Byproduct
Phosphoglycerokinase converts (2) 1,3-bisphosphoglycerate into (2) 3-phosphoglycerate and converting 2ADP to 2 ATP
Glycolysis Step 8:
Input
Enzyme
Output
Byproduct
Phosphoclyceromutase converts (2) 3-phosphoglycerate into (2) 2-phosphatoglycerate
Glycolysis Step 9:
Input
Enzyme
Output
Byproduct
Enolase converts 2-phosphoglycerate into (2) phosphoenolpyruvate (PEP) and producing 2 H2O
Glycolysis Step 10:
Input
Enzyme
Output
Byproduct
pyruvate kinase converts (2) phosphoenolpyruvate to pyruvate and converting 2 ADP to 2 ATP
What are the products of glycolysis?
2 ATP
2 NADH
2 Pyruvate
What is the energy investment phase of glycolysis?
Up to fructose 1,6 bisphosphate because two ATP are used
What is the energy generation phase of glycolysis?
After the formation of fructose 1,6-bisphosphate because we make 4 ATP but only net 2 because we used 2 in the first phase
Walk through the whole cycle
