The kinetics of the disintegration of baker's yeast cells in a bead mill is described as $$\frac{{dp}}{{dt}} = K\left( {{P_m} - P} \right)$$ , where P is the concentration of protein released, m is the maximum protein concentration achievable, K is the first order rate constant and is 0.5 h−1 for the system studied. The time required for the release of 90% of the intracellular proteins will be:
A. 10 h
B. 0.2 h
C. 4.6 h
D. None of the above
