The fractional saturation of an enzyme is 80% at a substrate concentration of 20 mM. In the presence of 5 mM of a competitive inhibitor the fractional saturation at the same substrate concentration is 40%. The Km for this reaction is mM, and the apparent Km is mM. The value of alpha is while the Ki of the inhibitor is mM.

The fractional saturation of an enzyme is 80% at a substrate concentration of
20 mM. In the presence of 5 mM of a competitive inhibitor the fractional
saturation at the same substrate concentration is 40%. The Km for this
reaction is
mM, and the apparent Km is
mM. The value of alpha is
while the Ki
of the inhibitor is
mM.
