How will the body respond if a normal biosynthetic pathway is blocked?
a.
The body will develop a different and completely new pathway to replace the blocked pathway.
b.
The body will not be able to produce the compounds of the blocked pathway and will eventually die.
c.
The body will use the reverse of the degradation pathway to make the necessary compounds.
d.
The body will not be affected by the blockage of a biosynthetic pathway.
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:

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
