Document Summary
Cell membranes and organelles: describe the components and structure of the cell membrane, describe the functions of major cell organelles and inclusions, identify microscopic appearance of major cell organelles and inclusions. Intracellular and extracellular environment of the cell is separated by pm. Inclusions extra stuff in cytoplasm (lipids, glycogen [pas], lipofusion [brown: cytosol fluid component of cytoplasm, everything between organelles pigment]) separated. In light microscope, not seeing pm, rather looking at the cell boundary which has an accumulation of proteins, allows to see where the pm would be. Integral protein functions: some are pumps, driven by atp, some are channels, like gap junctions. 2017-2018: receptors (responding to ligands in the periphery, linkers (anchor cell to ecm) (ex. collagen linker) important for maintaining the integrity of the tissue (cells would float about without it, enzymes (many functions, structural (hold cells together) Smooth er: no saccules, but tubules not associated with ribosomes.
