GLYCOLYSIS QUIZ

There are essentially three irreversible reactions that act as the driving force for the pathway

Glycolysis occurs in either direction

High levels of ATP keep the pathway going in a forward direction

The enzymes of glycolysis only function in one direction

activates fructose-1,6-bisphosphatase

activates phosphofructokinase

both (b) and (c)

inhibits fructose-1,6-bisphosphatase

1000 kcal

760 kcal

7.3 kcal

76 kcal

uses NADH to change the oxidation state of the substrate

uses ATP to add a phosphate group to the substrate

removes phosphate groups of substrates

removes water from a double bond

Phosphofructokinase

All of these

Hexose kinase

Pyruvate kinase

the techniques for isolating the phosphate donor are not refined enough

the high-energy phosphate donor is very short-lived and difficult to isolate

None of these

no such phosphate donor exists

Glycogen hydrolase

Glycogen semisynthase

Glycogen dehydrogenase

Glycogen synthase

Citrate and ATP

ATP and PEP

ATP and ADP

AMP and Pi

both (a) and (b)

the liver by phosphorolysis

the muscles by phosphorolysis

the muscles by hydrolysis

allosteric inhibition by ATP

allosteric stimulation by ADP

feedback, or product, inhibition by ATP

All of these
