Part I. True of False.
Circle T or F (read carefully)
T F 1. The linkage between
amino acids is called a peptide bond.
T F 2. Casein or milk production
is the most nearly perfect protein.
T F 3. Ketosis results from
insufficient blood glucose and the mobilization of fatty acids from adipose
tissue.
T F 4. The volitile fatty
acid, butyrate, in ruminants is the primary substrate for fatty acid synthesis.
T F 5. The unique fatty
acids contained in fish oils which may have a beneficial effect on atherosclerosis
in humans are the so-called omega-3 fatty acids
T F 6. A high lignin content
of a plant would tend to indicate the plant is probably mature and rain
has leached out the soluble carbohydrates.

of a protein is the % nitrogen absorbed from the GIT available for productive
body functions.
T F 8. Ruminant animals
have a more limited ability than non-ruminants to digest starch.

its own feces, it is called rumination
T F 10. Methane gas produced
in the gastric stomach of ruminants is a direct loss of energy to the animal.

principal end products of fermentation are the VFA, while in most animal
species the major product of CHO digestion is glucose.
T F 12. Pinocytosis, or
cell drinking, is an absorption process that requires large amounts
of energy from ATP.
