List of top Biology Questions on Enzymes asked in Indian Institute Of Technology Joint Admission Test for MSc

Restriction enzymes that recognize the same nucleotide sequence but cleave at different positions are called

$K_m$ and $V_{max}$ of an enzyme preparation are 5 µM and 30 $µM min^{-1}$ respectively. Considering, $K_i$ value of competitive inhibitor is 60 µM, the velocity ($V_0$) of this enzyme-catalyzed reaction in the presence of 200 µM of substrate and 600 µM of competitive inhibitor is _______ $ µM min^{-1}$ (rounded off to two decimal places).

Which of the following enzymes is absent in a person suffering from Alkaptonuria?

For an enzyme following Michaelis-Menten kinetics, when \([S]=K_M\) then, the velocity v is 
([S] is substrate concentration, \(K_M\) is Michaelis constant, \(V_{max}\) is maximal velocity)
