15. Substrate consumption in lag phase of microbial growth is primarily used for: (A) P, Q and S only (B) Q, R and S only (C) P, Q and R only (D) S only Where: P. turnover of the cell material Q. maintenance of intracellular pH R. motility S. increase in cell number
15. Substrate consumption in lag phase of microbial growth is primarily used for:
(A) P, Q and S only
(B) Q, R and S only
(C) P, Q and R only
(D) S only
Where:
P. turnover of the cell material
Q. maintenance of intracellular pH
R. motility
S. increase in cell number
Answer
Answer: (C) P, Q and R only
Explanation: During the lag phase, the microbial cells use substrates for turnover of cell material, maintenance of intracellular pH, and motility. The increase in cell number typically occurs after the lag phase during the exponential growth phase.
