Enzymes

Question 1

Catalyzes transfer of a phosphate group from ATP to a substrate →

Answer 1

Kinase (e.g., phosphofructokinase)

Question 2

Adds inorganic phosphate to a substrate without using ATP →

Answer 2

Phosphorylase (e.g., glycogen phosphorylase)

Question 3

Removes phosphate group from a substrate →

Answer 3

Phosphatase (e.g., fructose-1,6-bisphosphatase 1)

Question 4

Catalyzes oxidation-reduction reactions →

Answer 4

Dehydrogenase (e.g., pyruvate dehydrogenase)

Question 5

Adds hydroxyl (-OH) group to a substrate →

Answer 5

Hydroxylase (e.g., tyrosine hydroxylase)

Question 6

Transfers carboxyl (-COOH) groups with the help of biotin →

Answer 6

Carboxylase (e.g., pyruvate carboxylase)

Question 7

Relocates a functional group within a molecule →

Answer 7

Mutase (e.g., vitamin B₁₂–dependent methylmalonyl-CoA mutase)

Question 8

Joins two molecules using a source of energy (e.g., ATP) →

Answer 8

Synthase/Synthetase (e.g., using ATP, acetyl-CoA, or nucleotide sugar)
