Chapter 26, Problem 110P
Interpretation Introduction
Interpretation:
To explain whether the inhibitors of electron transport chain could help establish the order of carriers.

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 rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.
In the presence of drug B, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.
Why are some metabolic reactions coupled to the hydrolysis of ATP?
To drive the nonspontaneous reaction
To extend the half-life of enzymes
To increase the equilibrium constant
To bypass metabolic regulation
What is an allosteric inhibito
