Concentration of Sodium Chloride and the Rate of Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1

infection. Causes of Hypothyroidism Radiation therapy can also cause hypothyroidism. When radiation damages the cells‚ the thyroid gland has to work harder. Radioactive iodine treatment can also destroy the thyroid gland. Surgery and medications can also cause an underactive thyroid. The human body does not produce iodine‚ and iodine deficiency can cause hypothyroidism.

protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine residues in thyroglobulin molecules‚ inside the follicle cell. (www.vivo.colostate.edu/hbooks/pathphys/endocrine/thyroid/chem.html) This hormone regulates growth and controls the rate of chemical reactions in the body. This
