Hirul‚ Term Paper 4/25/2014 Thyroid Disease Thyroid is a small gland found at the base of your neck‚ just below your Adam ’s apple. The thyroid produces two main hormones called T3 and T4. These hormones travel in your blood to all parts of your body. The thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heart beats. All of these activities together are known as your body ’s metabolism. A thyroid that is working right

The Effects of HGH (Human Growth Hormone) In Enhancing Performance and Side Effects of Its Prolonged Use Human growth hormone (HGH) is produced by the pituitary gland within the body. One of its main functions is to increase growth in children and adolescents as they get older. HGH also helps regulate body composition‚ body fluids‚ muscle and bone growth‚ sugar and fat metabolism‚ and in some aspects‚ heart function. Human growth hormone can also be produced synthetically. The synthetic form of

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness
