6. classes of enzymes

Question 1

oxidoreductase

Answer 1

catalyzes redox rxns
eg lactate dehyrdogenase
usualy NAD+ and ADP involved

Question 2

transferases

Answer 2

catalyze transfer of functional groups

eg alanine transaminase (methyl group)

Question 3

hydrolases

Answer 3

catalyse hydrolysis (water in reactants).
they are special classes of transferase w/water serving as the receptor of the transfer gruop

Question 4

lyases

Answer 4

catayze the lysis of a substrate, generating a double bond, non hydrolytic, non oxidative, elemiation rxns

Question 5

isomerase

Answer 5

catalyze structural changes within a single molecule

eg isomeration rxn

Question 6

ligases

Answer 6

catalyze ligation, or joining of 2 substrates with ATP hydrolysis
