NUTR 3000 EXAM (MIDTERM 1 AND
2) QUESTIONS WITH CORRECT
ANSWERS
What is non protein nitrogen - CORRECT ANSWER- a nitrogen
containing compound in a diet that is not considered a true protein. Can
be used by certain organisms like ruminants to synthesize protein
What is a nutrient? - CORRECT ANSWER- a chemical component in
a diet required for maintenance, growth, reproduction, or lactation
What is an example of non protein nitrogen - CORRECT ANSWER-
ammonia
What is a protein? - CORRECT ANSWER- A sequence of amino
acids
Name an organism capable of digesting lignin - CORRECT ANSWER-
wood rotting fungi
What are the 10 essential amino acids? - CORRECT ANSWER-
Phenylalanine, valine, threonine, tryptophan, isoleucine, methionine,
histidine, arginine, leucine, lysine
What are the 4 main sources of water loss? - CORRECT ANSWER-
Urine, feces, sweating, Insensible
what are 5 functions of water in terrestrial animals - CORRECT
ANSWER- absorption, hydration, aids in hearing, temperature
regulation, metabolic functions
, Give an example of an external indicator - CORRECT ANSWER-

What is sequencing? - CORRECT ANSWER- planned order of
production of different feeds to reduce contamination and prevent
unwanted ingredients from carrying over into another feed
What is flushing? - CORRECT ANSWER- cleaning of equipment by
running a material through it to remove any residues of previous feeds.
Bile is stored where? - CORRECT ANSWER- gall bladder
Short chains of amino acids are called? - CORRECT ANSWER-
Peptides
When the absence of an essential amino acid results in disrupted protein
synthesis, what is this amino acid referred to as? - CORRECT
ANSWER- Liminting amino acid
What are the 3 volatile fatty acids? - CORRECT ANSWER- acetate,
propionate, butyrate
Why don't cattle produce salivary amylase? - CORRECT ANSWER-
Because it is too acid for their rumen pH. They have phosphate buffers
instead which help maintain pH levels and healthy gut microbiome as
well as prevent acidosis.
What is gluconeogenesis? - CORRECT ANSWER- The synthesis of
glucose using non-carbohydrates like amino acids.
What is allometric growth? - CORRECT ANSWER- When different
parts of an animals body grow at different rates. Ex. foals are all legs.
WHat is isometric growth? - CORRECT ANSWER- When all area's
of an animals body grow at the same rate. Ex. Fish
