GLYCOLYSIS QUIZ

Glycogen dehydrogenase

Glycogen synthase

Glycogen semisynthase

Glycogen hydrolase

the liver by phosphorolysis

both (a) and (b)

the muscles by phosphorolysis

the muscles by hydrolysis

ATP

a concentration gradient across a membrane

NAD+

ADP

76 kcal

760 kcal

1000 kcal

7.3 kcal

the gibbs free energy will be negative

the gibbs free energy will be positive

both (b) and (c)

more products will be formed

Nucleotides

Polysaccharides

Amino acids

Proteins

Allosteric control of the enzyme activity

Diffusional coupling between adjacent active sites

Genetic control of the enzyme concentration

Covalent modification of the enzyme

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

Glycolysis occurs in either direction

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

The enzymes of glycolysis only function in one direction

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

α-1,6 linkages

α-1,4 and β-1,6 linkage

α-1,4 and α-1,6 linkages

α-1,4 linkage
