Regents Biology
Carbohydrates Function:
quick energy energy storage structure
cell wall in plants
Examples sugars starches cellulose (cell wall)

BIG carbohydrates Polysaccharides Remember.. Poly- means Many
starch energy storage in plants
potatoes
glycogen energy storage in animals
in liver & muscles
cellulose structure in plants
cell walls

Regents Biology
Cowcan digest cellulose well; no need to eat other sugars
Gorillacan’t digest cellulose well; must add another sugar source, like fruit to diet
