All of these

Pyruvate kinase

Hexose kinase

Phosphofructokinase

phosphoglycerate kinase

glyceraldehyde-3 -dehydrogenase

Phosphofructokinase

pyruvate kinase

Glycogen dehydrogenase

Glycogen hydrolase

Glycogen semisynthase

Glycogen synthase

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

The enzymes of glycolysis only function in one direction

Glycolysis occurs in either direction

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

plasma membrane

mitochondrial matrix

intermembrane space

cytosol

uses ATP to add a phosphate group to the substrate

uses NADH to change the oxidation state of the substrate

removes water from a double bond

removes phosphate groups of substrates

the muscles by phosphorolysis

both (a) and (b)

the liver by phosphorolysis

the muscles by hydrolysis

Polysaccharides

Proteins

Nucleotides

Amino acids
