"That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid [goid 5615] [pmid 18229457] [evidence IDA]; A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration [goid 5739] [pmid 18086682] [evidence IDA]; The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae [goid 5743] [evidence IEA]; The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty-acid oxidation [goid 5759] [evidence IEA]; Small irregularly shaped intracellular vesicles to which endocytosed molecules are initially delivered [goid 5769] [pmid 11807771] [evidence IDA]; That part of the cytoplasm that does not contain membranous or particulate subcellular components [goid 5829] [pmid 18086682] [evidence IDA]; An invagination of the cell membrane of many eukaryotic cells, concerned in receptor-mediated selective transport of many proteins and other macromolecules across the cell membrane. During endocytosis it is converted into a coated vesicle. The coat is of clathrin [goid 5905] [pmid 11807771] [evidence IDA]; The external part of the cell wall and/or plasma membrane [goid 9986] [pmid 9243807] [evidence IDA]; A protein complex that phosphorylates cyclin-dependent kinases such as Cdc2 on Thr161 (or an equivalent residue); contains a catalytic subunit and a regulatory subunit, and some examples also include an assembly factor [goid 19907] [pmid 11445587] [evidence IDA]; Small membrane-bounded organelle formed by pinching off of a coated region of membrane. Some coats are made of clathrin, whereas others are made from other proteins [goid 30135] [pmid 11807771] [evidence IDA]; A multiprotein complex that consists of at least three proteins, CD14, TLR4, and MD-2, each of which is glycosylated [goid 46696] [pmid 17164250] [evidence IDA]"
