What is hemoglobin composed of? - 4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? - Porphyria Porphyria - Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? - Methemoglobin is a form of hemoglobin that contains ferric [Fe3+] iron and has a decrea...

NRNP 6566 MidtermStudy Guide NRNP 6566 Mid-term Study Guide Week 1 to 5 Week 1 1. Describe the cytochrome P450 system. Describe how inducers and inhibitors affect the cytochrome system and how that affects the half-life of medications. Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as ...
