Anatomy and Physiology
Atkins or “Fadkins” ? Questions:
1. First, find out what nutrients Janine and Mitchell are talking about. Using a biology textbook and the resources listed, describe what the following molecules are and what they are used for in the human body. List some specific examples of each. Also list major dietary sources of each. a. Proteins- macromolecules made of amino acids. Proteins have many functions in the body. Some sources of proteins are whole-grain cereals, dark breads,rice, beans, and meat.
-forming collagen and keratin
-transporting molecules in the blood
-quicken chemical reactions
b. Carbohydrates- molecules that contain carbon,hydrogen, and oxygen.
Some sources of carbohydrates are sugars, breads, cereals, vegetables,
-quick source of energy
-best for the brain and nerve tissues
-there are simple and complex carbohydrate
Fats- type of lipid and usually come from animals. Sources can be lard
-needed for vitamin absorption
-creating cell lipids and steroids.
-excess energy is stored as fat in the human body
2. Janine made this statement: “... if your brain doesn't get carbs- well, glucose, anyway- you get really cranky. You have to have enough carbs.” Find out if Janine is right. How does the nervous system use glucose? Answer: Yes, Janine is right. Glucose is used as an immediate source of energy. But it is only a simple carbohydrate (which means it is low in carbon atoms).
3. Janine also said: “ If you eat way too much protein and not enough carbs you can ruin your kidneys forever because of all the nitrogen you have to process breaking down the protein. Find out if Janine is right about this, too. Check a biology textbook for...
