α-1,4 and α-1,6 linkages

α-1,4 and β-1,6 linkage

α-1,6 linkages

α-1,4 linkage

Pyruvate kinase

Hexose kinase

Phosphofructokinase

All of these

Amino acids

Nucleotides

Polysaccharides

Proteins

Dinitrophenol

neither (a) nor (b)

Both (a) and (b)

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

uses ATP to add a phosphate group to the substrate

removes phosphate groups of substrates

removes water from a double bond

uses NADH to change the oxidation state of the substrate

mitochondrial matrix

intermembrane space

plasma membrane

cytosol

activates phosphofructokinase

both (b) and (c)

inhibits fructose-1,6-bisphosphatase

activates fructose-1,6-bisphosphatase

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

The enzymes of glycolysis only function in one direction

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

Glycolysis occurs in either direction
