2. Specific product formation rate is constant
3. Specific product formation rate is proportional to specific growth rate
4. Specific growth rate decreases with increasing substrate concentration
Options:
(A) P-1, Q-2, R-4, S-3
(B) P-3, Q-2, R-1, S-4
(C) P-2, Q-1, R-3, S-4
(D) P-2, Q-3, R-4, S-1
Answer
Answer: (B) P-3, Q-2, R-1, S-4
Explanation: Growth associated product formation means the product formation rate is proportional to the growth rate (3). Non-growth associated product formation means the product formation rate is constant (2). Product inhibition causes a decrease in growth rate with increasing product concentration (1). Substrate inhibition leads to decreased growth rate with increasing substrate concentration (4).
