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? Adipose Tissue is a connective tissue in which fat cells are stored. They give cushion to vital organs and keep the body at warm temperatures. (2) Define epidemic. An epidemic is a highly contagious disease that spreads quickly through a region effecting many people with the same symptoms. (3) Define obesity. A condition in which a person has stored too much fat and they are excessively overweight. (4) How could we have an obesity epidemic? We could have an obesity epidemic because Americans eat very similar unhealthy foods that supply the body with too much energy triggering the storing of fat cells as adipose tissue. (5) What are the main obesity related illnesses? Diabetes, High Blood Pressure, and Heart Disease. (6) How does the liver protect the body from alcohol? The liver puts its regular duties on hold to break down the alcohol and flush it out of the body. (7) Where does excess energy go? It is stored as fat cells in the adipose tissue. (8) Why do we have so much excess energy in our diet? We consume too much sugar to break down and burn. (9) If we didn't have adipose tissue where could we put the excess energy? Is this OK? We would store it in our organs...NO this is not ok because our organs would have no time to do their own processes instead they would be breaking down fat and using it to burn the energy. (9) Humans have much more body fat than our closest relatives the chimpanzees. What is a possible evolutionary reason for this? We have taught ourselves to over consume energy. The animals know just how much they need to survive. We live to eat. They eat to live. (10) Adipocytes (Fat cells) are filled with fat called triglycerides. Describe the triglyceride structure and why it contains so much energy. The triglyceride structure is a chain of three fatty acids made up of a high-energy combination of hydrogens and carbons. (11) What happens to adipocytes when we gain weight? (a lot of weight) If we have excess lipids in our body they are absorbed into the existing fat cells, but when those are overloaded, the fat cells divide and absorb more! (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? Adipocytes release leptin. Leptin is only released in a girl's body when there is enough fat storage to support the gonadal hormones as well.
