How does dnp affect the process of cellular respiration?

Dinitrophenol (DNP) disrupts cellular respiration by uncoupling oxidative phosphorylation in mitochondria. It allows protons to leak across the inner mitochondrial membrane, bypassing ATP synthase, which reduces ATP production. As a result, cells increase their metabolic rate to compensate for the loss of ATP, leading to increased heat generation and potential overheating. This uncoupling effect ultimately diminishes the efficiency of energy production in the cell.
