The large purple structure with an arrow represents a transmembrane potassium channel and the direction of net potassium movement. Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell.
The inner membrane of mitochondria is similar in lipid composition to the membrane of bacteria. This phenomenon can be explained by the endosymbiont hypothesis of the origin of mitochondria as prokaryotes internalized by a eukaryotic host cell. In pig heart mitochondria, phosphatidylethanolamine makes up the majority of the inner mitochondrial ...
Mitochondrial membrane transport proteins, also known as mitochondrial carrier proteins, are proteins which exist in the membranes of mitochondria. They serve to transport [2] molecules and other factors, such as ions, into or out of the organelles. Mitochondria contain both an inner and outer membrane, separated by the inter-membrane space, or ...
Voltage-dependent anion channels, or mitochondrial porins, are a class of porin ion channel located on the outer mitochondrial membrane. [1][2] There is debate as to whether or not this channel is expressed in the cell surface membrane. [3][4][5] This major protein of the outer mitochondrial membrane of eukaryotes forms a voltage-dependent ...
The calcium is taken up into the matrix by the mitochondrial calcium uniporter on the inner mitochondrial membrane. [61] It is primarily driven by the mitochondrial membrane potential. [55] Release of this calcium back into the cell's interior can occur via a sodium-calcium exchange protein or via "calcium-induced-calcium-release" pathways. [61]
Respiratory complex I, EC 7.1.1.2 (also known as NADH:ubiquinone oxidoreductase, Type I NADH dehydrogenase and mitochondrial complex I) is the first large protein complex of the respiratory chains of many organisms from bacteria to humans. It catalyzes the transfer of electrons from NADH to coenzyme Q10 (CoQ10) and translocates protons across ...
VDAC1. Voltage-dependent anion-selective channel 1 (VDAC-1) is a beta barrel protein that in humans is encoded by the VDAC1 gene located on chromosome 5. [4][5] It forms an ion channel in the outer mitochondrial membrane (OMM) and also the outer cell membrane. In the OMM, it allows ATP to diffuse out of the mitochondria into the cytoplasm.
Mitochondria associated membranes are involved in the transport of calcium from the ER to mitochondria. This interaction is important for rapid uptake of calcium by mitochondria through Voltage dependent anion channels (VDACs), which are located at the outer mitochondrial membrane (OMM). This transport is regulated with chaperones and ...
