A $60ml$ enzyme extract obtained from plant tissue had an activity of $2{10}^{3}U.$ After purification, a velume of $30ml$ obtained and an artivity of $6{10}^{3}U$ If the toal probein coscentrations of the crude and purified forms of the exyyme were $250mg$ and $150mg$ respectively.

Calculate the;

$($i$)\%$ yield of parification

$($i$0)$ total enints of the crude enzyme

$($tit$)$ specific activity of both crude and purified form of the enzyme

$($iv$)$ fold panfication
