Cofactor Study guides, Revision notes & Summaries

What is cellular metabolism? - a controlled set of biochemical reactions that occur in living organisms in order to maintain life What is an enzyme? - a protein, or group of proteins, that catalyze (speed up) chemical reactions What is unique about enzymes? - the enzyme is not consumed during the reaction and can be used repeatedly by the cell What is a cofactor? - a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions Do cofactors serve as regu...

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 for hormone synthesis and br...

I. Enzymes and coenzymes. Regulation of metabolism. 1. Enzymes: definition, structure and properties of enzymes. - Enzymes definition are biological catalysts, which determine the rate and pattern of chemical transformations in biological systems that underlie the meta- bolic pathways. According to their chemical nature, all the enzymes are pro- teins. Shortly speaking, enzymes are designated as biological catalysts of a protein nature. Under the catalytic action of enzymes biomolecules (s...
