1 sugar = monosaccharide
2 sugars = disaccharide
|maltose
mono = onesaccharide = sugar

Regents Biology
Different Diets of Herbivores Cow
___________ cellulose well; no need to eat other sugars
Gorilla___________ cellulose well; must add another sugar source, like fruit to diet
Regents Biology
Helpful bacteria How can cows digest cellulose?
bacteria live in their stomachs & help digest cellulose-rich (grass) meals
Eeeew…Chewing
cud?
