Question

7. Which protein is responsible for determining cell shape opposite cell poles? A. AmiC B. Ftsz C. MinCD D. MreB E. Z ring and moving chromosomes to 8. Which protein is responsible for inhibiting Z-ring formation at positions other than at the center? A. AmiC B. Ftsz C. MinCDE D. MreB E. Z ring 9. Which of the following is true of growth curve? A. 4 distinct phases are observed in a batch culture B. Cells at the log phase are the most susceptible to disinfectants and antibiotics C. Damaged cells are repaired during the lag phase D. Growth rate is constant and maximal during the log phase E. All of the above are true 10. Which of the following is NOT true about the generation time? A. Also called doubling time B. Is measured during the stationary phase C. Required for the population to double in size D. Varies depending on species of microorganism E. All of the above are true 11. Which of the following is NOT a reason for the occurrence of a lag phase in a bacterial growth curve? A. The cells may be old and depleted of ATP, essential cofactors, and ribosomes that must be synthesized before growth can begin B. The medium may be different from the previous growth medium so that the cells must synthesize new enzymes to use different nutrients C. The organisms may have been injured and require time to recover D. The cells become dormant E. All of the above are potential reasons 12. Microbial population is most uniform in terms of chemical and physical properties during the exponential phase of growth. A. True B. False

Explanation / Answer

1. MreB

2. MinCDE

3. All the above are true

4. B is not true. Because generation time is measured at exponential growth phase

5. The cells become dormant is not a reason.

6. True
