    GO ID   Ontology GO Term Definition
    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    6869   Lipid Transport  The Directed Movement of Lipids Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. Lipids Are Compounds Soluble in an Organic Solvent But Not or Sparingly in an Aqueous Solvent. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    5640   Nuclear Outer Membrane  The Outer I.e. Cytoplasm Facing Lipid Bilayer of the Nuclear Envelope; Continuous with the Endoplasmic Reticulum of the Cell and Sometimes Studded with Ribosomes. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5768   Endosome  A Membrane Bounded Organelle to Which Materials Ingested by Endocytosis Are Delivered. 
    5794   Golgi Apparatus  A Compound Membranous Cytoplasmic Organelle of Eukaryotic Cells Consisting of Flattened Ribosome Free Vesicles Arranged in a More or Less Regular Stack. the Golgi Apparatus Differs From the Endoplasmic Reticulum in Often Having Slightly Thicker Membranes Appearing in Sections As a Characteristic Shallow Semicircle So That the Convex Side (cis or Entry Face) Abuts the Endoplasmic Reticulum Secretory Vesicles Emerging From the Concave Side (trans or Exit Face). in Vertebrate Cells There Is Usually One Such Organelle While in Invertebrates and Plants Where They Are Known Usually As Dictyosomes There May Be Several Scattered in the Cytoplasm. the Golgi Apparatus Processes Proteins Produced On the Ribosomes of the Rough Endoplasmic Reticulum; Such Processing Includes Modification of the Core Oligosaccharides of Glycoproteins and the Sorting and Packaging of Proteins For Transport to a Variety of Cellular Locations. Three Different Regions of the Golgi Are Now Recognized Both in Terms of Structure and Function: Cis in the Vicinity of the Cis Face Trans in the Vicinity of the Trans Face and Medial Lying Between the Cis and Trans Regions. 
    5829   Cytosol  The Part of the Cytoplasm That Does Not Contain Organelles But Which Does Contain Other Particulate Matter Such As Protein Complexes. 
    5886   Plasma Membrane  The Membrane Surrounding a Cell That Separates the Cell From Its External Environment. It Consists of a Phospholipid Bilayer and Associated Proteins. 
    10008   Endosome Membrane  The Lipid Bilayer Surrounding an Endosome. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    8289   Lipid Binding  Interacting Selectively and Non Covalently with a Lipid.
