METABOLISMThis chapter discusses the set of necessary chemical reactions that occur in the human body to maintain homeostasis.

*1. What is metabolism? Compare and contrast anabolism and catabolism. Metabolism is the set of chemical reactions that occur in living organisms to maintain homeostasis. The processes allow individuals to reproduce, grow, maintain their structures and respond to their environments. Metabolism is divided into two catagories: Cabolism and Anabolism. During catabolism, large molecules (ex: Carbs and fats) are broken down causing energy to be released. This energy is needed for anabolism, which creates body heat and muscle contraction. Anabolism energy is also used to build the complex molecules known as carbs, fats and proteins. The processes promote growth of new cells and tissues and to store energy for future use.

2. What are enzymes and what role do they play in metabolism? Enzymes are molecules that catalyze (meaning to speed up) the rate chemical reactions. In metabolism, enzymes play a role in releasing and storing energy. They are crucial to metabolism because they allow organize to drive desirable reactions that require energy and won't occur by themselves, and couple with spontaneous reactions that release energy. They act as catalysts to allow these reactions to occur quickly and efficiently. Some enzymes work to break apart large molecules, while others work to promote the creation of molecules. Enzymes also allow the regulation of metabolic pathways in response to changes in the cell or signals from other cells.


3. What is basil metabolic rate (BMR)? The BMR is the metabolic rate at which a person's body burns calories (measured by the rate of oxygen consumption) of an awake, relaxed person that hasn't eaten in 12 to 14 hours and is at a comfortable temperature.

*APPLICATION:1. My BMR is 1268.6. 2. My daily caloric needs are at 1744/per day. 3. Honestly, I think I am fine for right right now. I am 5'2" and barely weigh 100 lbs. I have the metabolism of a gerble and am very active with my almost 4 year old daughter. However, if I wanted to increased my BMR for some reason, such as if I were overweight, I could lose weight, eat regular healthy meals (which I should be doing anyway) and get good physical exercise.***1. Find a product that says that it will boost your metabolism. Research the physiology behind how it boosts a person's metabolism. Summarize what you learned in your research. I found Ignite Maxx diet pills!
Ignite says to boost metabolism by: "Ignite Maxx™ utilizes a patented process of micro-encapsulation to load high-strength capsicum extract into an inert central core, which delivers functionally
effective levels of capsaicinoids while minimizing the oral and gastric irritation that unprotected capsicum can cause." Capsaicinoids, the active compounds in hot chili peppers, show an ability to encourage lipolysis (fat breakdown). This product contains digestive enzymes, caffeine, green tea extract, rhodiola root extract, black pepper extract and rasberry ketone. All are related to faster calorie burning, thus bumping up metabolism.

2. Why do crash diets not work on a physiology level? Crash diets are used to quickly lose weight, usually by cutting an extreme amount of calories. You can lose pounds fast, but it won't help to leave them off and is definitely not healthy. The body doesn't get the nutrients and calories it needs to function and have energy. With lower energy, the body and mind becomes fatigued. A drastic change in caloric intake lowers the BMR. It also causes a lower intake of sodium meaning that you can lose too much water making you dehydrated. This also means that you have lost mostly water weight and the pounds will return shortly.
