To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs.  These drugs can each pick up electrons from specific intermediates in the pathway as shown above. You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table. In the presence of drug A Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No) In the presence of drug B Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No)

To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs.  These drugs can each pick up electrons from specific intermediates in the pathway as shown above.

You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table.

In the presence of drug A Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No)

In the presence of drug B Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No)
