A hyperbolic binding curve differs from a sigmoidal binding curve in that the hyperbolic curve
A)has a single equilibrium constant for oxygen binding.
B)binds more oxygen after the initial proteins first bind oxygen.
C)shows cooperativity.
D)binds up to four molecules of oxygen.
E)All of the above.

Question

Quizplus · Accepted Answer

A hyperbolic binding curve has a single equilibrium constant for oxygen binding, whereas a sigmoidal binding curve exhibits cooperative binding and has multiple equilibrium constants. Therefore, options B, C, D, and E are incorrect.
