calorie

transfer of heat energy to the skin and then to the external environment is known as

conduction

a transfer of heat energy to air that is continually flowing away from the skin is known as

convection

the amount of nutrients in the blood

does not change very much and remains relatively constant

heat absorbed by the process of water vaporization is called

evaporation

which hormone lowers blood glucose levels

insulin

a good source of iron in the diet is

meat

essential amino acids

must be in the diet

glycolysis changes glucose into

radiation

detoxifies various poisonous substances such as bacterial products and certain drugs

the liver

plays an important role in the mechanical digestion of lipids because it secretes bile

the liver

synthesizes several kinds of protein compounds

the liver

fats not needed for catabolism are anabolized to form

triglycerides

use of foods

an anaerobic process

uses no oxygen
