Question

In the accelerated phase, cell starts to _________

(a) increase and the division rate increases to reach a maximum

(b) decrease and the division rate increases to reach a maximum

(c) increase and the division rate decreases to reach a maximum

(d) increase and the division rate increases to reach a minimum

I had been asked this question during an internship interview.

Origin of the question is Cell Growth Kinetics topic in portion Homogenous Reactions of Bioprocess Engineering

Answer 1

Correct option is (a) increase and the division rate increases to reach a maximum

Easy explanation: This is a brief transient period during which cells start growing slowly. In fact, acceleration phase connects the lag phase and log phase.
