Answer:
This is because the hemoglobin molecule changes its shape, or conformation, as oxygen binds. The fourth oxygen is then more difficult to bind. The binding of oxygen to hemoglobin can be plotted as a function of the partial pressure of oxygen in the blood (x-axis) versus the relative Hb-oxygen saturation (y-axis).Explanation:

The correct answer is d. both excitation and inhibition.
There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).
Explanation:
main difference between competitive and noncompetitive inhibition is that competitive inhibition is the binding of the inhibitor to the active site of the enzyme whereas noncompetitive inhibition is the binding of the inhibitor to the enzyme at a point other than the active site.
