Enzyme Names

Question 1

Kinases

Answer 1

Transfer phosphoryl groups from ATP/GTP to an acceptor molecule (ex: hexokinase)

Question 2

Phosphorylase

Answer 2

Displacement reaction where inorganic phosphate is the attacking group and gets covalently bonded to an acceptor molecule (ex: glycogen phosphorylase)

Question 3

Phosphatases

Answer 3

Catalyze the hydrolysis of the phospho-ester bond (ex: fructose 1,6 bisphosphatase)

Question 4

Synthase

Answer 4

Catalyze condensation reactions without using ATP or GTP as an energy source (ex: citrate synthase)

Question 5

Synthetase

Answer 5

Catalyze condensation reactions using ATP or GTP as an energy source (ex: succinyl CoA synthetase)

Question 6

Oxidases and Oxygenases

Answer 6

Catalyze oxidation reaction in which oxygen is the electron acceptor

Question 7

Dehydrogenases

Answer 7

Catalyze oxidation-reduction reactions using electron carriers (such as NAD+) (ex: malate dehydrogenase)
