You are exploring oxygen binding to myoglobin in a solution where oxygen is present at 10 mM and myoglobin is present at 1 M. If oxygen binding to myoglobin is diffusion limited, what is the maximum rate for oxygen binding to myoglobin? Assume oxygen is a sphere with radius 0.2 nm and diffusion constant of 2.4E-5 cm2/s, myoglobin is a sphere with radius 2 nm and diffusion constant of 1E-6 cm2/s.

a.

c.

2.53E2 M/s

d.

4.16E2 M/s

e.

4.16E10 M/s
