Document Summary

Detail 1: plasma membrane (lipid bilayer: controls exchange of materials between inside and outside of cell regulates cell"s chemical composition. Nuclear pore: special permeable sites in nuclear envelope that allow specific macromolecules to pass between nucleus and cytoplasm, each pore is bounded by eight protein particles. Peroxisome: arises in the cytosol from lipids and proteins, contains enzymes that create hydrogen peroxide that is used for fat breakdown, detoxification, and other metabolic processes. Free ribosomes: scattered throughout cytosol composed of two subunits, synthesize proteins that function within cytosol. Bound ribosome: attached to the rer membrane, composed of two subunits synthesize proteins in the cytoplasm destined for secretion. Basal body of cilium: identical in structure to a centriole. Cross section of cilium, showing 9 + 2 arrangement of microtubules with dynein arms w w w . p e r m a c h a r t s . c o m.
