WebJun 1, 1998 · Abstract Mitochondrial uncouplers, such as 2,4 dinitrophenol (DNP), increase the cellular respiration by decreasing mitochondrial membrane potential (delta psi). We show that this respiratory effect can be transient or even prevented in isolated liver cells depending on the exogenous substrate used (dihydroxyacetone vs. octanoate or proline). WebApr 8, 2024 · How does the poison cyanide act upon the aerobic respiration? Cyanide is a poison that inhibits the last cytochrome of the respiratory chain, interrupting the ATP formation and thus leading the cell to death. 1.
