Basic Nutrition Concepts Flashcards
The sum of all the physical and chemical processes taking place in living organisms
Metabolism
Processes that involve the degradation or decomposition of complex compounds to simpler materials
Catabolism
Synthesis of simpler materials into complex compounds
Anabolism
Most energy comes from _________ and _________
carbohydrates and fats
Determines the amount of food that is actually absorbed by an animal and therefore the avilability of nutrients
Digestibility
the total amount of energy theoretically available from food
Gross Energy
The actual amount of energy available to the animal
Net Energy
Six Major Nutrient Categories
Water, carbohydrates, protein, fat, vitamins, minerals
Water loss occurs from….
Urinary, fecal, evaporation
Water gain comes from…
Food, metabolic water, drinking
Carbohydrates are converted into ____ for storage
Fats
Cells are made of _______
Proteins
Nutritional value of the protein depends on ________ and ______ _____
digestibility and amino acids
In dogs, arachidonic acid can be synthesized from linoleic acid but ____ must get it in their diet.
cats
Good source of energy and increases palatability. Produces roughly twice as much energy as carbohydrates.
Essential Fatty Acids
Essential enzymes, enzyme precursors, and coenzyme in many body metabolic processes
Vitamins (functions)
Water soluble vitamins
B & C
Fat Soluble vitamins
A, D, E, K
Vitamins not stored in the body and must be replenished each day
B, C
Signs of vitamin A deficiencies
Night blindness, retarded growth, poor quality skin and hair
Signs of vitamin D deficiencies
Ricketts, poor eruption of permanent teeth
Signs of vitamin E deficiencies
Reproductive failure, brown bowel syndrome
Signs of vitamin K deficiencies
Increased clotting time and hemorrhage
Signs of vitamin C deficiencies
Slowed healing, increased susceptibility to disease
