Explain the concept of substrate inhibition in Monod kinetics.

• Substrate inhibition is when the enzyme activity remains constant at high substrate concentrations.

• Substrate inhibition is when the enzyme activity is not affected by substrate concentration.

• Substrate inhibition is when the enzyme activity increases at high substrate concentrations.

• Substrate inhibition is when the enzyme activity decreases at high substrate concentrations.

Solve for the Monod constant (Ks) using the Haldane inhibition model.
