Q268
Most microorganism function at their best within a pH range
A.
6.0 - 7.5
AnswerB.
7.5 - 8.5
C.
4.5 - 5.5
D.
At any stage
Answer: Option A
Solution
Answer: Option A
Solution:
Most of the microorganisms function at their best within the neutral pH range i.e. of 6.0 - 7.5. The pH is important for the proper functioning of organisms as the enzymes that catalyze the chemical reactions of life require a specific pH to function. Moreover, the increase and decrease in pH can cause denaturation of biochemical like proteins and make them non-functional, resulting in cell death.
