The core temperature of mammals affects membrane fluidity, metabolic reaction rates, and protein structures 

The major end-products of energy substrates produced by fermentation of plant fibers include:

Consider how the body acquires lipids from the diet and address the following questions (10 points total). Describe the three places where lipase enzymes are involved in lipid absorption and postabsorptive lipid metabolism. (5 points).   Provide a definition for lipoprotein and describe their role in lipid absorption and postabsorptive lipid metabolism. (5 points).

Which of the diet component below is the least digestible by ruminants?

The rumen microbial organisms include bacteria, protozoa and fungi. The bacteria:  

As feedstuffs enter the rumen, most protein is hydrolyzed to amino acids which are degraded to ammonia and energy. The maximum output by microbes to re-synthesize amino acids and form microbial proteins depends on:

Which source of carbohydrate would provide the least apparent digestible energy to monogastric animals if the sources were provided in equal amounts in the diet?

Which of the following best describes a positive energy balance in an animal?
