Produced by Anterior Pituitary Gland 2. Targets of hGH are Bone‚ muscle‚ skin‚ adipose tissue and liver 3. Effects of hGH are to promote protein synthesis‚ encourage use of fats for fuel‚ and elevate blood glucose by decreasing uptake and increasing glycogen breakdown 4. Regulation of hGH is hormonal 5. hGH is a protein 6. hGH is water soluble 7. hGH is protein kinase activation 8. Endocrine disorders - Hyper secretion causes Giantism in children and Acromegaly in Adults Hypo secretion - Dwarfism

Sports Drinks and Homeostasis Gail B. Wortmann Iowa Learning Online 2001 Iowa Teacher of the Year Teacher Notes: Sports Drinks and Homeostasis Personal notes from the author: If you want students to have a rich discussion about a topic‚ the topic has to be “on their agenda.” Students need to have something from their past experience to contribute to make the discussion truly engaging. Most students have tried sports drinks at some time in their life‚ and therefore‚ have experiences

which is the preferred energy source for working muscles. These foods are bread‚ rice‚ pasta‚ breakfast cereals‚ fruits and tubers. You can drink additional servings of carbohydrates a few days before competition‚ to saturate the liver and muscle glycogen (the form is stored as glucose). Fluids: Keep the body well hydrated during and after training and competition. Be careful with the consumption of beverages containing caffeine. The diet should be low in:

Skipping breakfast can actually backfire on you‚ and cause you to gain weight. Going without food increases the production of insulin in your body‚ which can cause your body to store more fat. b. The longer you go without eating‚ the more glycogen your muscles use‚ and the less energy you have. c. Depending on age and gender‚ your body needs a minimum amount of nutritional elements‚ such as vitamins‚ minerals‚ fiber‚ calories and fat‚ to keep organs functioning properly. Eating breakfast

nucleus. The nucleus includes DNA. Cytoplasm: The cytoplasm of a cell is the material in the inside of the cell which is semi-fluid and is able to flow slowly and all chemical reactions within cells are carried out in there. Complex sugars including glycogen and melanin which is the pigment responsible for skin and hair colour are in the cytoplasm. These chemicals are the basic living materials that a cell needs. Organelles are the various components of a cell with a specific structure and function

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

back into glucose when required. It can be found in 2 forms: * The polysaccharides of amylose (50-500 glucose units in a straight line) * Amylopectin (Which contains up to 100000 glucose units in a branch like structure) Polysaccharides Glycogen: is the bodies’ equivalent to starch. It is stored in the liver and muscles and is Brocken down into glucose when energy is required. Pectin: pectin substances are compounds which are found in cells between the cells of fruit and some root vegetables
Premium Glucose Nutrition Digestion
This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

Hypotonic solutions may be used (with care) to rehydrate the tissues of extremely dehydrated patients. In mild cases of dehydration‚ drinking hypotonic fluids (such as apple juice and sports drinks) usually does the trick. 3.4 Lysosomes degrade glycogen and certain lipids in the brain at a relatively constant rate. In Tay-Sachs disease‚ an inherited condition seen mostly in Jews from Central Europe‚ the lysosomes lack an enzyme needed to breakdown a glycolipid abundant in nerve cell membranes. As
