The shape of the curve will become hyperbolic and will resemble that of myoglobin.
None of the above.
The position of the curve will move to the left but remain a sigmoidal curve.
The shape of the curve will remain sigmoidal but it will shift to the right.
The position and shape of the curve will not change.
