Document Summary

Plasma membrane separated the internal environment from the external environment. Selective regulation of what goes in and out. All the cellular contents between the membrane and nucleus. Two components: cytosol: intracellular fluid of the cytoplasm. Water, dissolved solutes and suspended particles: organelles: inside the cytosol. Each one has a certain shape and function. Nucleus mitochondira large organelle that has the cells dna chromosomes (single molecules of dna) inside the nucleus has genes that control cell structure and function. Fluid mosaic model the arrangement of the plasma membrane is like a sea of moving fluid lipids that contains different proteins that float freely or are anchored at specific locations. The lipid bilayer: 2 layers of three lipid molecules: Glycolipids: 5: lipids are amphipathic (have both polar and nonpolar sides) Phospholipids have a hydrophilic phosphate head and 2 hydrophobic fatty acid tails. Integral protein: extend into or though the lipid bilayer and embed in it.
