WebMay 4, 2016 · During the lag phase of the bacterial growth cycle, synthesis of RNA, enzymes and other molecules occurs. The log phase (sometimes called the exponential phase) is a period characterized by cell doubling. The number of new bacteria appearing per unit time is proportional to the present population. WebFinal answer. Step 1/3. When conducting an antibiotic sensitivity test, it's important to test the bacteria during the log phase of growth rather than the stationary phase. This is because during the log phase, the bacteria are actively dividing and have a higher metabolic rate, making them more susceptible to the effects of antibiotics.
