Document Summary

Introduction: cell is small and simple when viewed with the light microscope that it is difficult to conceive that each cell is a living entity. Basic cell organelles: golgi apparatus: responsible for packaging proteins from the rough endoplasmic reticulum into membrane-bound vesicles. Often form in groups of 10 to 20 known. Proteins are packaged into vesicles that transport them to. Golgi: smooth or agranular endoplasmic reticulum: lacks ribosomes. Dna strands during cell division: nucleolus, dense body within the cell nucleus which contains the specific dna that produces the. Membrane proteins: membrane proteins have many different functions, receptors for the attachment of chemical hormones and neurotransmitters, enzymes that help with chemical reactions or breakdown molecules. Ion channels or pores that allow water-soluble substances, like ions, into the cell: membrane-transport carriers that transport molecules across the membrane (many include gated channels, cell-identity markers, like antigens or glycoproteins.
