Some enzymes require a nonprotein component. Cytochrome oxidase requires Cu^2+ t

Question

Some enzymes require a nonprotein component. Cytochrome oxidase requires Cu^2+ to catalyze the reaction. In this case, Cu^2+ is a ___ of this enzyme. Yeast alcohol dehydrogenase (YADH) requires NAD^+ for this enzyme to properly function. NAD^+ is and organic molecule. In this context, NAD^+ is acting as a ___ for this enzyme. On the graph below, show an enzyme with no inhibitor, with a competitive inhibitor, and with a noncompetitive inhibitor. Make sure to label each line on the graph. Briefly explain the graph. (ie, why does the graph of an inhibitor look a specific way?)

Explanation / Answer

(8) Some enzymes require a nonprotein component. Cytochrome oxidase requires Cu2+ to catalyze the reaction. In this case, Cu2+ is a cofactor of this enzyme. Yeast alcohol dehydrogenase requires NAD+ for this enzyme to properly function. NAD+ is an organic molecule. iN this context, NAD+ is acting as a coenzyme for this enzyme.
