Answer:
The correct answer is A they will no longer be able to perform aerobic respiration.
Explanation:
Rotenone is an isoflavonid compound which act an inhibitor of electron transport chain in mitochondria.Rotenone generally blocks the transfer of electrons from from NADH CoQ dehydrogenase or complex 1 to ubiquinone.
As electron transport is blocked the reduced coenzymes such as NADH,FADH2 are unable to be oxidized.
As a result cells exposed to rotenone will no longer be able to perform aerobic respiration.
Answer:
The correct answer is- log phase
Explanation:
Most antibiotics work on actively growing bacteria and the log phase is the phase when bacteria is metabolically most active and actively divide. Bacteria is most susceptible to antibiotics in log phase because the target of most antibiotic is cell wall, protein, DNA and in log phase new proteins, DNA and cell wall is actively synthesized in large amount.
Therefore antibiotics get their target easily during the log phase of bacteria which allows the bacteria to become most sensitive towards antibiotics in this phase. Therefore the right answer is log phase.
