Dr. Bad has developed a way to damage the ATP-binding cassette transporter (ABC transporter) on a cell. The cell's ABC transporter can no longer bind and use ATP when it's transporting substances.

Which of the following statements best describes how this damage would effect the transport of substances in the affected cell?

(Choice A)

Substances at a low concentration outside the cell would be more rapidly transported into the cell, where there is a high concentration.

(Choice B)

Substances at a high concentration outside the cell would not be transported into the cell, where there is a low concentration.

(Choice C)

Equilibrium would be established between all substances inside and outside of the cell.

(Choice D)

Substances at a low concentration outside the cell would not be transported into the cell, where there is a high concentration.

The answer is; Choice D

ABC transporters are transmembrane proteins that enable active transportation of substances across the cell membrane. The protein is important in the movement of substances against their concentration gradient using ATP energy. ATP binding causes it to change conformation and bind the molecule being transported.
