$i$. All enzymes are proteinaceous.
$ii$. Enzyme becomes more active at the temperature of $60^{\circ}C$ to $70^{\circ}C$.
$iii$. Enzymes have one or two active sites where substrate binds with the enzyme.
$iv$. Any increase or decrease in specific $pH$,enzyme activity is always enhanced.
$v$. Enzymes remain active to catalyze again after completion of first reaction.
