What do extracellular enzymes (exoenzymes) act on?
Substances outside the cell
What are the typical exoenzymes?
they are hydrolytic enzymes.
What do hydrolytic enzymes do?
split polymers into monomers by inserting water
What do hydrolytic enzymes break down?
break down high molecular weight substances that are too large to pass through the cell membrane into low molecular weight materials that can be transported into the cell
Polysaccharides?

Proteins
Monosaccharides
Glycerol+ Fatty Acids
Amino Acids
What are intracellular enzymes?
Function where?
