How can the inhibition constant (KI) be derived similarly to the Michaelis constant (KM) by substituting substrate concentration with inhibitor concentration?

• A. KI is derived by substituting the substrate concentration in the KM equation with the inhibitor concentration.
• B. KI is derived by substituting the product concentration in the KM equation with the inhibitor concentration.
• C. KI is derived by substituting the reaction velocity in the KM equation with the inhibitor concentration.
• D. KI is derived by substituting the enzyme concentration in the KM equation with the inhibitor concentration.
