Fccp protonophore
WebCarbonyl cyanide-p-trifluoromethoxyphenylhydrazone (FCCP) is an ionophore that is a mobile ion carrier. It is referred to as an uncoupling agent because it disrupts ATP … A protonophore, also known as a proton translocator, is an ionophore that moves protons across lipid bilayers or other type of membranes. This would otherwise not occur as protons cations (H ) have positive charge and hydrophilic properties, making them unable to cross without a channel or transporter in … See more The facilitated transport of protons across the biological membrane by anionic protonophore is achieved as follows. 1. The anionic form of the protonophore (P ) is adsorbed onto one side (Positive) of the biological … See more • Chemiosmosis See more

Still, PCP shows … WebApr 14, 2024 · Our work suggests that SUR2A-55 can regulate ROMK and that ROMK is important in mitochondrial coupling. The blockade of ROMK in WT cardiomyocytes depolarizes Δψm to a greater extent when mitochondria are stressed with the protonophore FCCP. This observation is also present and appears heightened in the …
