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 just like fat. its another name for fat.

(2) Define epidemic. - Epidemic is a disease that appears as new cases in human population . (3) Define obesity. - Obesity is not due to any defect in adipose tissue. Its an issue of energy balance. If you are consuming more calories than the amount of calories you are burning off, the body must cope with that energy surplus, making you obese.

(4) How could we have an obesity epidemic? - We could have an obesity epidemic if we were to eat tons of fast food and cut out fat in our diets, which would cause us to eat more and especially eat more carbohydrates to make up the loss of fat that we eliminated from our diets.

(5) What are the main obesity related illnesses? - Heart disease, diabetes, high blood pressure

(6) How does the liver protect the body from alcohol? - It tries to detox the large quantities of liquor. It removes the bad stuff (toxins)

(7) Where does excess energy go? - The excess energy is going to the fat tissue, which is absorbing the packets of energy we put in our mouths.

(8) Why do we have so much excess energy in our diet? - We have so much excess energy in our diets because we consume more of the wrong foods. We don't have a balanced diet. We may be eating too many of the wrong sugars.

(9) If we didn't have adipose tissue where could we put the excess energy? Is this OK? - the excess energy would go to the liver. It would cause extreme liver swelling, liver failure and sometimes liver-bearer death. So its not okay for the excess energy to end up in the liver.

(9) Humans have much more body fat than our closest relatives the chimpanzees. What is a possible evolutionary reason for this? - We have too many foods to choose from. We have more processed foods to choose from than the chimpanzees.

(10) Adipocytes (Fat cells) are filled with fat called triglycerides. Describe the triglyceride structure and why it contains so much energy. tri - meaning 3. There are three fatty acid that are made of carbons and hydrogens. they are arranged in a high energy way and have a lot of energy in them. Hormoes reglulate the release of the trigcerides from fat tissue so they meet the body requirements of energy.

(11) What happens to adipocytes when we gain weight? (a lot of weight) -They are having to work harder because when we gain weight we are stretching them out.

(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? - Hormones that are released are epinephrine and norepinephrine. - When a girls fat stores become dense the body releases leptin and signals the brain to set the pulsing azis of gonadal hormones in motion.
