Cisplatin's effectiveness weakens when exposed to excess intracellular glutathione because which mechanism occurs?

💡 Explanation

Cisplatin's anti-cancer activity decreases due to a ligand substitution reaction where glutathione displaces the chloride ligands. This disrupts cisplatin's ability to bind to DNA because glutathione competes for binding sites, therefore reducing efficacy rather than enabling other pathways.
