Is condition 2 competitive or noncompetitive inhibition? Condition 2: y = 10 x + 10 Condition 1: y = 5 x + 5
Ans is Non competitive
So we use condition 1as untreated and condition 2 as inhibitor traeted.So to know whether it is competitive or non competitive we hve to find vmax and km of both the condition by using formula given below as it follows straight line equation in the condition shown above.
1/V=(km/Vmax)1/S+1/Vmax refer to Y=mx+c
So if use the condition 1 here than 1/Vmax is equal to 5 because it is intercept of graph and hence Vmax= 0.2
Use this value for km/Vmax=5 and keep vmax value 0.2 so we will get Km =1.0
Same do for condition 2 here than 1/Vmax is equal to 10 so Vmax=0.1
use this value ofor Km/Vmax=10 and hence Km will be 1.0
This results shows that addition of inhibitor leads to change in Vmax but unchanged Km so this clearly relate to Non competitive inhibitor because in the presence of the inhibitor because some of the enzyme molecules will always be “out of commission.Where as in case of Competitive Vmax is the maximum velocity of the enzyme. Competitive inhibitors can only bind to E and not to ES. They increase Km by interfering with the binding of the substrate, but they do not affect Vmax because the inhibitor does not change the catalysis in ES because it cannot bind to ES.

Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is equal to normal, and as the substrate concentration is increased more and more, the rate of reaction remains the same as the normal rate. What can be concluded about the unknown substance? Select...
Compare competitive and noncompetitive inhibition Question An enzyme is placed in the presence of an unknown substance to determine whether the substance is an inhibitor. As the substrate concentration is increased, the rate of reaction is compared to the normal rate of reaction. Initially, the rate is slower than normal, but as the substrate concentration is increased more and more, the rate of reaction approaches normal. What can be concluded about the unknown substance? Select the correct answer below: O...

1. Explain the difference between competitive and noncompetitive inhibition. I am having a hard time understanding the difference between the two. Could someone please explain the difference between the two? 2. Could someone also give an example of one drug that acts as an enzyme inhibitor and explain its mechanism of action.
Compare competitive and noncompetitive inhibition Question Suppose that glycerol (CH,OHCH(OH)CH,OH) is a substrate in an enzyme-catalyzed biochemical reaction and propylene glycol (CH OHCH(OH)CHZ) is an inhibitor of the reaction. Would you expect propylene glycol to be a competitive or noncompetitive inhibitor? Why? Select the correct answer below: O It is likely that propylene glycol would be a competitive inhibitor because it easily binds to glycerol. O It is likely that propylene glycol would be a competitive inhibitor because it has...
