What molecule in glycolysis could be considered the substrate in substrate-level phosphorylation?
Biphosphoglycerate
In glycolysis, 3-phosphoglycerate is converted to 2-phosphoglycerate. The enzyme that catalyzes this reaction is
Phosphoglycerate mutase
Consider phosphofructokinase, what statement is true?
High ATP inhibits the enzyme, fructose-2,6-biphosphate activates the enzyme
Which enzyme requires NAD+?
Glyceraldehyde dehydrogenase
Which enzyme is responsible for the conversion of glucose-6-phosphate into fructose-6-phosphate?
Phosphoglucoisomerase
Pyruvate kinase is allosterically inhibited by
High concentrations of ATP
Many of the reactions of glycolysis have free energy changes that are close to zero. What is most likely to be true for those reactions?
They are reversible reactions
In glycolysis, fructose-6-phosphate is converted to fructose-1,6- bisphosphate by phosphofructokinase. Select the true/reasonable statements.
- This step is reversible in cellular conditions
- This step is a point of control
- This step requires ATP
- Fructose-1,6-bisphosphate is committed to become pyruvate and yield energy
What cells only use glycolysis for ATP production?
Erythocytes
