6
4
enz that catalyses the conversion of aldose sugar to ketose sugar wold be classified as
transperases
isomerases
oxidoreductases
hydrolases
in which of the following types of enzymes water may be added to a C=C bond without breaking the bond:
hydrolase
hydratase
hydroxylase
esterase
lock and key hypothesis was given by
emil fischer
pasteur
fredrick fischer
rahul
maximum activity of most enz is at a pH between
2-3
4-5
5-9
7-12
when [S] equals to Km, which of the following conditions exist
half the enz molecules are bound with the substrate
velocity of the reaction is half of Vmax
velocity is independent of substrate concentration
enz is completely saturated with substrate
in competitive inhibiton
Km increases without affecting Vmax
decreases both Km and Vmax
increases bith Km and Vmax
decreases Km without affecting Vmax
enz acting on peptide bond includes
hexokinase
chymotrypsin
synthetase
glucose 6 phosphate
oxidases are usualy inhibited by
cyanides
fluorides
salts of Hg
salts of Ag
factors affecting enzyme activity are
temperature
pH
oxidation
all the above
A+B
