you have to talk about that intracellular and extracellular enzyme crap...

points you have to talk about are that:

-you need a fermenter
-you need a source from where enzymes can be collected (eg yeast)
-you need a feedstock which contains molasses
-conditions - 27 celsius and alkaline pH
-mention a paddle to stir liquid

then finally say what is required to obtain intra/extracellular

intra - feedstock filtered, microorganisms filtered. its then crushed and extracted
extra - feedstock filtered and extracted

thats it...write this and u are assured full marks on any type of this question
