At steady state the interior free-substrate balance gives

B_{i} = - J

. Substituting this into the interior free-carrier balance gives

0 = J + k (c_{e} - c_{i})

. Therefore

c_{i} = c_{e} + J / k .

(1)

For positive inward throughput there are more free carriers facing inward: release of transported substrate must be followed by outward return of empty carriers at net rate

k (c_{i} - c_{e}) = J
