what are they made of?
bonds?

Answer 4

starch- more highly branched

Question 7

define inulin

Answer 7

breaks down to fructose NOT glucose

found in tubers

Question 8

cellulose

Answer 8

insoluble fiber bc humans can’t break down beta 1-4 bonds

Answer 9

1. amylase
2. pancreatic enzymes
3. brush border enzymes (intestinal enzymes)
