Fat is Good? SCI Human Biology - 1 Assigned: 10/18 Due: 10/19 Fat is doing us a favor...You may need to look up some of the answers on the internet or your book. (1) Liposuction suctions out adipose tissue. What is adipose tissue? Fat, connective loose, energy storing fat. (2) Define epidemic. Large scale, rapid outbreak of highly contagious disease or condition. (3) Define obesity. 25 lbs over ideal body weight (4) How could we have an obesity epidemic? It has become a wide spread problem, too many “people are gaining too much weight and putting themselves at risk.” (5) What are the main obesity related illnesses? Diabetes, high blood pressure, heart disease (6) How does the liver protect the body from alcohol? The liver detoxifies the alcohol consumed. (7) Where does excess energy go? Into fat cells, adipose tissue. (8) Why do we have so much excess energy in our diet? Because foods/diets are too prossesed, refined, and all around unhealthy. (9) If we didn't have adipose tissue where could we put the excess energy? Is this OK? The fat would go to the liver; No it wouldn’t be okay, the liver would swell, fail, and could be fatal. (9) Humans have much more body fat than our closest relatives the chimpanzees. What is a possible evolutionary reason for this? the body has been creating more and more fat cells. (10) Adipocytes (Fat cells) are filled with fat called triglycerides. Describe the triglyceride structure and why it contains so much energy. Triglyceride is made up of carbons and hydrogens positioned in a high-energy configuation intended to expand much large than its size to withstand food intake. (11) What happens to adipocytes when we gain weight? (a lot of weight) Fat cells initiate cell division, but fat cells rarely die. (12) Adipose tissue can be an endocrine gland too. Which hormone do adipocytes release, and how does this signal the body that it is time for puberty? It secretes “leptin, an essential player in reporduciton” it signals the body when the stored fat is “sufficiently dense.”
