Animals eat woody plants, lack enzyme important in what process?

Question

Animals that eat woody plants lack an enzyme that is important in what process?
A. Dehydration synthesis of glucose monomers
B. Hydrolysis of cellulose
C. Digestion of Cellulose
D. answers A, B, and C
E. Answers B and C

i was leaning for C, because lignin (which is in wood) is hydrophobic, so i dont think an animal would eat wood for hydrolysis of cellulose... which would cut out answer D.
but im terrible at biology and my professor doesnt explain anything.

Answer 1

nitrogen is the key to this and cellose is what nitrogen can deal with that animals do not. so C: is your answer.


if not oops! www.stopthedump.com

europeans dumping on american soil with chopped up cars for there own benefit. i find this disgusting! they should deal with their own trask and waste!

Answer 2

E. hydrolysis is part of the process of digesting cellulose. animals don't have the enzyme to perform it, nut the microbes in the animals bodies do.
