Molecule A is generated inside the cell at a constant rate of λA. It decomposes irreversibly, and in a first order manner in terms of the concentration of A, into
molecule B:k A B⎯⎯→
he rate of reaction is k. B diffuses to the ECF. The diffusion coefficient is kdb. The concentration of B in the ECF is close to 0 all the time. Both parameters, k and kdb, are positive.
Write down the rate equations for a (the concentration of A) and b (the concentration of B). Explain briefly. Is there a conservation of mass? Why or why not?
