Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

Outline and Evaluate Biological Explanation for Mental Illness The Biomedical model of Mental Illness states that metal illness is caused by either a physical problem with the brain‚ for example that some schizophrenic patients have parts of there hippocampus missing. Genetics‚ meaning that you inherit a genetic pre-disposition to depression or some other mental illness as someone in your close family had that mental illness‚ or down to neurotransmitter (serotonin‚ dopamine...) imbalances in

The nurse would first assume an authoritative role to help the patient stay safe. Explain to the patient that his safety is your primary concern and will have to take precedence over other needs or wishes. Other questions that J.B. would need to answer are: Do you have a plan? Is so‚ what is it and is the plan specific? Do you have the means to carry out this plan? (access to a

POLYPHENOLS CONTENT AND ANTIOXIDANT ACTIVITY IN SKY FRUIT (Fructus Swietenia macrophylla) KERNELS AND SEED COATS ABSTRACT In all aerobic organisms‚ production of free radical is balanced by antioxidant defense system. Antioxidants are very important in terms of preventing oxidative stress that may lead to several degenerative diseases. Studies have been done on the sky fruit leaves‚ bark and seeds and they were reported to have many medicinal value. The aim of this study is to evaluate

Solution) ➢ Sodium chloride (1% solution) ➢ Sulfite salt (1% solution) ➢ Samples (Potato‚ Banana‚ Apple) Enzymatic Browning: Enzymatic browning (oxidative) is a reaction between oxygen and a phenolic substrate catalyzed by polyphenol oxidase result in orthoquinone‚ which in turn rapidly polymerized to form brown pigments or melanin. This is the common browning that occur in cut fruits and vegetables [pic] Phenolase enzymes that have been isolated from food sources are oligomers

Therefore‚ it will be presumed that the result of this experiment by isolating the polyphenol oxidase within the potato extract through the oxidation of 5mM dopa solution with highly concentrated enzymatic preparation of polyphenol oxidase with a buffer as the diluent will indicate a rapid increase in the rate of the reaction as well as the amount of activity present in the potato extract. Proposing that Vmax
