GLYCOLYSIS QUIZ

The enzymes of glycolysis only function in one direction

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

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

Glycolysis occurs in either direction

Hexose kinase

All of these

Pyruvate kinase

Phosphofructokinase

primarily in animals excluding particles

only in eukaryotes

in all living organisms

only in yeast

is stored as fat.

is lost as heat

remains in the products of metabolism

is used to reduce NADP

Amino acids

Polysaccharides

Proteins

Nucleotides

The Fo base-piece of ATP synthase (without the Fl subunit)

neither (a) nor (b)

Dinitrophenol

Both (a) and (b)

phosphoglycerate kinase

Phosphofructokinase

glyceraldehyde-3 -dehydrogenase

pyruvate kinase

the techniques for isolating the phosphate donor are not refined enough

None of these

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

no such phosphate donor exists

the liver by phosphorolysis

the muscles by phosphorolysis

the muscles by hydrolysis

both (a) and (b)
