Starch is a polysaccharide formed by plants as a way to store the large amounts of glucose produced during photosynthesis. Animals are able to break down starch into individual glucose molecules, which makes starch an important food source. Cellulose, a polysaccharide made up of glucose, is a very strong material that serves as the primary structural component of plants. Most animals are not able to break cellulose down into glucose. However, cellulose in the food that we eat is important because it serves as dietary fiber that regulates digestion. Name Differences and Similarities.

please help it would mean a lot

Sorry dude i dont know this one :(

OpenStudy (anonymous):

dang. well thanks anyways, appreciate it. :)

I'm confused as to what you don't understand about how to answer this. Take the two paragraphs and then say what is different in the two and what is similar...

OpenStudy (anonymous):

im lazy.......

OpenStudy (agreene):

thats unfortunate

OpenStudy (anonymous):

please help?

OpenStudy (anonymous):

ok XD ill do it now!!!!!

hey...both starch and cellulose are made up of same glucose units.the starch moiety will have alpha 1->4 linkage, whereas cellulose will have beta 1->4 linkage..we all have amylase enzyme(which can breakdown ur starch alpha1->4 linkage but not beta 1->4 linkage) in our saliva and thats y carbohydrate digestion is said to start from ur mouth itself....cellulose cannot be avoided in case of having greens..,they cannot be digested as i said above but it just helps in cleaning our body...some ruminants like cows, horses have symbiotic relations with microbes in their stomach which will help in digesting cellulose.. for ex:termites have symbiotic relation with triconympha in intestine....but we dont have such symbiotic relations..and one main difference is that starch is a storage polysaccharide but cellulose is a structural polysaccharide.....hope that helps :-)
