Level 1
what enzyme is used to convert G-6-P to F-6-P?
Phosphoglucoisomerase
How many enzymes needed to convert 1 Glucose to 2 3-carbon pyruvate?
10
Conversion from BPG to PEP, how many ATP is formed?
2 ATP from 2 ADP
Summary of Phase 1
-Phosphorylation of Glucose
- Conversion to 2 molecules Glyceraldehyde-3-phosphate
- 2 ATP used
what is the product of DHAP with triosephosphateisomerase?
G-3-P (D-Glyceraldehyde-3-phosphate)
Under Anaerobic conditions, what products that 2 pyruvate convert to?
- 2 Lactate OR 2 Ethanol + 2CO2
The first reaction of Glycolysis is phospholarylation of glucose which consumes energy (ATP).
So, does net energy gain?
Yes (favorable)
Summary of Phase 2:
-
-
- Conversion of glyceraldehyde-3-phosphate to pyruvate
- coupled formation of 4 ATP and NADH
Where does glycolysis occur?
Cytosol
What is this enzyme?
The enzymes phosphorylate glucose for most cell.
Hexokinase
When are Glucokinase operative?
Only when glucose levels are high and the glucose excess use eventually stored as glycogen.
What is this reaction?
Raction commits the cell to metabolizing glucose and not to conversion to another sugar or storage.
Reaction 3: Phophofructokinase
How many molecules of 3- carbon pyruvate was/ were formed after glycolysis ?
Two
Which reaction was the phospho group transferred from C3 to C2?
This is definition of what ?
It is one of the primary sites for regulation of glycolysis. It is regarded as the glycolytic valve.
