Did you know?

WebThe inhibition can be overcome with an increase in [S], so you can still reach Vmax (no changes to Vmax) if the [S] is high enough. Since you need more S to reach Vmax, you need more S to reach Vmax/2, aka increase in Km What is the hallmark of the lineweaver-burk plot for competitive inhibition? No change in the y-coordinate (Vmax). WebCompetitive inhibition can be overcome by addition of substrate, which increases an enzyme's chance of finding real substrate. Let's look at how this might work. Say you're trapped in a...

WebCompetitive inhibition describes inhibitors that have exclusive affinity for the enzyme and compete for substrate binding. • Mixed inhibitors bind to the enzyme and the … WebNon-competitive inhibitors can have a variety of affects on the enzyme (lowering Vmax, increasing Km, completely inactivating the enzyme) The sign that the inhibitor is non-competitive is that the inhibition can NOT be overcome with high substrate concentration. Lower Vmax, even at very high [S]

WebOne of the most well known equations to describe single-substrate enzyme kinetics is the Michaelis-Menten equation.
