in the place where I live there's a shop named competitive scissors [it's a tailor]
So I always remember that competitive inhibitors cross the vectors at the Y axis in Lineweaver-Berk Plot

Kompetitive Inhibition: Km Increases; no change in Vmax.
Non-kompetitive inhibition: No Km change, but Vmax decreases.

Km/Vmax = Competitive/Noncompetitive. When Km increase = Competitive. When Vmax decrease = Noncompetitive

The mnemonic (vMAX) ENVY always helped me since biochem

E - efficacy decreases
N - non-competitive
V - Vmax decreases
Y - y-intercept (1/vmax)

Thumbs Up

first you need to know that always Vmax will represent the y axis and
and the Km will represent the x axis...

Vmax will represent the Efficacy of a Drugs on the Y axis if increase
the Vmax will increase the Efficacy of that Drugs, if the Vmax drecrease
will Efficacy there by Noncompetitive inhibitor always drecrease the
Effect of Vmax.. competitive inhibitor dont affect the vmz


Km will represent the Potency on the X axis and if the Km increase
will decrease the pontency of the Drugs, if the Km decrease will increase the pontency of a Drug competitve inhibitor will increase the Km

Now your job is to learn which Drugs are competitive inhibitor and which drugs are Noncompetitive inhibitor.....

I hope you answered you question.

competitive inhibitors:
"Competition is hard because we have to travel more kilometers (km) with the same velocity"
