Answer:
Chemotherapy drugs and other toxins are actively pumped out of cancer cells by transmembrane proteins.
Explanation:
Drugs inside the cell can be inactivated by oxidation and / or conjugation with glutathione, such as glutathione S-transferases, playing an important role in detoxification. However, conjugation is not enough for drug elimination. And this is where the GS-X pumps appear. Transporter proteins, such as Mrp protein, act as GS-X pumps. The PgP, Mrp and Bcrp proteins function as expulsion pumps, thus reducing the intracellular accumulation of drugs, causing resistance in cancer cells.
