Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific

colour change was compared with the colour chart on the Uristix® bottle. The detection of glucose in urine is based on the presence of two enzymes‚ glucose oxidase and peroxidase. The first enzyme‚ glucose oxidase‚ catalyses the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose. The second enzyme‚ peroxidase‚ catalyses the

N-acetyl cysteine (NAC) is a small molecule containing a thiol group. It was first introduced as a mucolytic drug in the 1960s. NAC has been found to have an antioxidant effect‚ acting as a free-radical scavenging agent and a precursor of reduced glutathione (GSH). These effects provide the organism with crucial defense mechanism towards

Magnesium‚ an abundant mineral in the body‚ is naturally present in many foods‚ added to other food products‚ available as a dietary supplement‚ and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body‚ including protein synthesis‚ muscle and nerve function‚ blood glucose control‚ and blood pressure regulation [1-3]. Magnesium is required for energy production‚ oxidative phosphorylation

After blocking for nonspecific binding using 3% BSA‚ the membrane was incubated with rabbit anti-SRL polyclonal antibodies at 1:5‚000 dilutions followed by treatment with a secondary antibody‚ horse radish peroxidase (HP) conjugated anti-rabbit IgG at 1:2‚000 dilutions (Biorad USA). Bound secondary antibodies were detected by Immuno-StarTm HP reagent (Biorad USA) and the blots were exposed to X-ray film followed by

the result of Parkinson’s disease found in aging individuals however‚ the consumption of MPTP dramatically accelerates this process in the course of days and not years (Hanson et al.‚ 2015). Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it

Curcumin has been found to be a potent inhibitor of tumour growth and cell proliferation. This activity is linked to curcumin’s antioxidant effect and free radical scavenging effect (Akram et al‚ 2010). It inhibits cancer development and progression‚ thereby targeting multiple steps to malignancy. It has the ability to act like a blocking agent thereby inhibiting the initiation step of cancer by preventing the activation of carcinogen‚ and also as a suppressing agent thereby inhibiting malignant

hypothyroidism (high TSH) that leads to permanent thyroid failure‚ with lifelong thyroid hormone replacement indicated. Hashimoto thyroiditis is typically associated with positive thyroid autoantibodies‚ including antithyroglobulin and antithyroid peroxidase antibodies. Radioactive iodine uptake is variable in Hashimoto thyroiditis and is not part of the diagnostic workup of hypothyroidism. Choice "D" is not the best answer.

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a 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
