i have just started my AS in biology and just wanted some advice on this question really: do the cells need lots of RER to make many proteins which then travel to the golgi body to be added to carbs/lipids that have been made in SER. and are these modified proteins then enzymes which are obviously needed in the small intestine to digest molecules? thanks x
