| GO:0008270 | zinc ion binding | molecular_function | Binding to a zinc ion (Zn). [GOC:ai] |
| GO:0001580 | detection of chemical stimulus involved in sensory perception of bitter taste | biological_process | The series of events required for a bitter taste stimulus to be received and converted to a molecular signal. [GOC:go_curators] |
| GO:0005576 | extracellular region | cellular_component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| GO:0005615 | extracellular space | cellular_component | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. [ISBN:0198547684] |
| GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
| GO:0070062 | extracellular exosome | cellular_component | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
