Introduction: Cytochrome c oxidase plays a vital role in cellular respiration by accepting e- from cytochrome c and transferring them to an acceptor oxygen molecule in the final step of electron transfer chain. Carbon monoxide and cyanide are few of the inhibitor of this enzyme. 4 Fe2+ -cyt c + 8H+ + O2 4 Fe3+ -cyt c + 2H2O + 4H+ [out] Cytochrome c oxidase locates to the inner membrane which separates the mitochondrial matrix from the intermembrane space. However‚ Potato tubes can

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

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
