When you performed the same kinetic study in the presence of an
inhibitor, you obtained a new line that had y-intercept 3 and x-intercept
-0.3. Based on this information select all correct statements about this
inhibitor.
This is mixed inhibitor.
When this inhibitor is present apparent Km of enzyme decreases.
This inhibitor prevents substrate from binding to the enzyme.
This is uncompetitive inhibitor.
When this inhibitor is present apparent Vmax of enzyme decreases.
When this inhibitor is present apparent Km of enzyme increases.
This inhibitor can bind to either enzyme or enzyme-substrate complex.
