Mitochondrial respiratory chain ppt
Webmitochondria structure: four components: a) outer membrane: permeable to certain ions and small moleculeses b) intermembrane space: respiratory chain proteins are representative c) matrix: most of the metabolic … Web30 dec. 2024 · This is accomplished by uncoupling the electron transport chain from the ATP synthesis. This uncoupling is a hormonally controlled process based on the presence of a mitochondrial proton channel called thermogenin. The hormone norepinephrine increases production of free fatty acids, which open the thermogenin channel.
