synthesized by an organism and must be obtained through diet.
What is arguably the most important function of cells? Right Ans - the
production of the thousands of different proteins the body needs to function.

What role does the lymphatic system play in nutrition? Right Ans -
supports elimination of waste products in the body.
What role does the endocrine system play in nutrition? Right Ans -
Regulation of hunger
appetite & digestion
Entry of nutrients into cells (insulin)
Mobilization of energy (glucagon, Lipase, Gh-growth Hormone, cortisol)
Anabolic (muscle building or healing)
Catabolic (muscle breakdown)
What is the most important nutrient and why? Right Ans - Oxygen. Oxygen
is NOT stored in the body and must be continuously supplied by respiration.
Oxygen deprivation is the at-root cause of all cancer.
