nner and outer mitochondrial membranes enclose two spaces: the matrix and intermembrane space
vInner and outer mitochondrial membranes enclose two spaces: the matrix and intermembrane space
Outer membrane. Contains channel-forming protein, called porin Permeable to all molecules of 5000 daltons or less Inner membrane(Impermeability) Contains proteins with three types of functions (1)Electron-transport chain: Carry out oxidation reactions 2)ATP synthase: Makes ATP in the matrix; (3) Transport proteins: Allow the passage of metabolites Intermembrane space: Contains several enzymes use ATP to phosphorylate other nucleotides Matrix: Enzymes; Mit DNA, Ribosomes, etc
