Hello,
I am wondering if I have a correct grasp on what is meant by the term catalytic activity. I though that the activity of an enzyme is the Vmax/Km value, and this dictates how similar two enzymes or proteins are in terms of function. When i did my Altius half length test there was a question asking about the effects on Catalytic activity and Substrate binding when Km was increased and Vmax was not changed. I thought this would mean a decrease in catalytic activity, as Km is on the bottom of the fraction, however the correct answer was that catalytic activity was unchanged. I am wondering whether my thought process is wrong?
-thanks
