16. Hydrolysis: Amylase maltase Starch - ------- maltose -------2 glucose Glycogen - storage CHO of animal tissues - large molecule and highly branched - can easily be broken down to yield glucose Cellulose – most abundant organic molecule in the planet - chief structural material in plants; provides rigidity - indigestible in man due to complex arrangement of glucose - provides bulk and stimulates bowel movement - enzyme cellulase from bacteria and protozoans digest cellulose to yield glucose
