Most Eukaryotic ABC Transporters Are Involved in Exporting Small Molecules

True/False

Most eukaryotic ABC transporters are involved in exporting small molecules from the cytosol. In this subset of the ABC transporters, does the small molecule bind better to the ATP-bound (B) or the ATP-free (F) transporter? Write down your answer as B or
F. Hint: The ATP-bound transporter "faces outward."
