On the basis of hypothetical binding curve given below, which of the following statement is INCORRECT

#Section 2: General Biology

Ɵ Theta represents the fraction of binding sites occupied by ligand, the concentration of ligand at which half the binding sites are occupied
A hypothetical binding curve for a ligand L. The [L] at which half of the available ligand binding sites are occupied is equivalent to 1/Ka, or Kd.
The curve has a horizontal asymptote at Ɵ Theta = 1 and a vertical asymptote at [L] = -1/Kd.
Ɵ Theta is analogous to Vmax for Michaelis- Menton enzymes.
