  • Cytosol
    on Jun 28, 2011 in The Cytoplasm
     At one time, it was believed that the cytoplasm intervening between the discrete organelles and deposits was unstructured. This belief was reinforced by the use of homogenization and centrifugation of the homogenates to yield fractions consi...
  • Cytoplasmic Deposits
    on Jun 26, 2011 in The Cytoplasm
    Cytoplasmic deposits are usually transitory components of the cytoplasm, composed mainly of accumulated metabolites or other substances. The accumulated molecules occur in several forms, one of them being lipid droplets in adipose tissue, adrenal...
  • Intermediate Filaments
    on Jun 25, 2011 in The Cytoplasm
    Ultrastructural and immunocytochemical investigations reveal that a third major filamentous structure is present in eukaryotic cells. In addition to the thin (actin) and thick (myosin) filaments, cells contain a class of intermediate-sized filamen...
  • Actin Filaments
    on Jun 24, 2011 in The Cytoplasm
    Contractile activity in muscle cells results primarily from an interaction between two proteins: actin and myosin. Actin is present in muscle as a thin (5–7 nm in diameter) filament composed of globular subunits organized into a double-stranded...
  • Microtubules
    on Jun 23, 2011 in The Cytoplasm
    The cytoplasmic cytoskeleton is a complex network of microtubules, actin filaments (microfilaments), and intermediate filaments. These structural proteins provide for the shaping of cells and also play an important role in the movements of organel...
  • Proteasomes, Peroxisomes, & Secretory Vesicles
    on Jun 22, 2011 in The Cytoplasm
    Proteasomes Proteasomes are multiple-protease complexes that digest proteins targeted for destruction by attachment to ubiquitin. Protein degradation is essential to remove excess enzyme and other proteins that become unnecessary to the cell afte...
  • Lysosomes
    on Jun 21, 2011 in The Cytoplasm
    Lysosomes are sites of intracellular digestion and turnover of cellular components. Lysosomes (Gr. lysis, solution, + soma, body) are membrane-limited vesicles that contain a large variety of hydrolytic enzymes (more than 40) whose main function i...
  • Golgi Complex (Golgi Apparatus)
    on Jun 21, 2011 in The Cytoplasm
    The Golgi complex completes posttranslational modifications and packages and places an address on products that have been synthesized by the cell. This organelle is composed of smooth membrane-limited cisternae (Figures 2–21, 2–22, and 2–23)...
