Q

Amylose is the starch

A

without branches

17
Q

(Referring to the Lecture notes p.8,) Amylopectin is a branched starch molecule because it has

A

alpha-1,6-glycosidic bond

18
Q

Suppose the amount of enzymes is not limiting, glycogen has the highest efficiency among all polysaccharides to form glucose for releasing energy because

A

it has more branches to provide a larger surface area for enzymes to hydrolyse

19
Q

What is the monomer for cellulose?

A

beta glucose
