Textbook Question
Chapter 3, Problem 4TYK
Cows can derive nutrients from cellulose because
a. they produce enzymes that recognize the shape of the glucose-glucose bonds and hydrolyze them.
b. they re-chew their cud to break down cellulose fibers.
c. their digestive tract contains microorganisms that can hydrolyze the bonds of cellulose.
d. they convert cellulose to starch and can digest starch.

Why are cattle able to survive, grow, and reproduce on a plant diet which does not contain most of the essential amino acids required for their health?
Select one:
a.
Their saliva has cellulase and can therefore digest cellulose present in plant cell walls
b.
Like rabbits, cattle can re-ingest their feces
c.
Bacteria in their rumen synthesize essential amino acids from digested plant material
d.
They are unique in that they can synthesize all essential amino acids in their liver from a variety of metabolic precursors
e.
They are autotrophs
Which of the following are differences between starch and glycogen?
A. Starch is a mixture of amylose and amylopectin while glycogen is a pure biopolymer.
B. The amylopectin instarch has more branches than glycogen.
C. Starch is the storage form of glucose in plants while glycogen is in animals and humans.
D. The branches in amylopectin is alpha 1->6 while itis beta 1-->6 in glycogen.
E. Starch reacts more intensely with Lugol's reagent than glycogen.
What is the difference between starch and cellulose that makes one digestible and the other not digestible to humans? Explain and illustrate.
