What happens when a suitable substrate binds to an enzyme? - ANSWER-The active site amino acids bond with the substrate Cyanide binds to cytochrome oxidase at a site where the substrate oxygen would normally bind. This is an example of - ANSWER-competitive inhibition an example of a catabolic reaction is - ANSWER-lactate fermentation what is an anabolic process that is endergonic and endothermic? - ANSWER-CH₄ +2O₂ → CO₂ + 2H₂O ATP yields 7.3 kcal/mol of free energy and it i...

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 ...

Cytochrome c oxidase correct answers An enzyme responsible for electron transfer in the ETC, so inhibiting it would slow or stop the ETC. Dosing of Blast Phase Chronic Myeloid Leukemia (BP-CML) cells with cyanide would result in: correct answers Reduced intercellular ATP and apoptosis or necrosis. Cyanide binds to cytochrome c oxidase and prevents electron transfer. Inhibiting cytochrome C oxidase would decrease ATP production. thus, large dose would also cause cell death (apoptosis or ne...
