What must happen to polysaccharides before they can be transported into the cell? What enzymes are important in this process?
Polysaccharides such as starch, glycogen and cellulose as well as proteins need to hydrolyzed into oligomers or monomers prior to transport into the cell.
An endoglucanse such as a-amylase can chop the chains in monomers, dimers and oligomers (glucose, maltose and dextrin.
B-amylase is exoglucanase that removes the disaccharide maltose and glucoamylase removes glucose units from the amylose non-reducing end.
