Document Summary

Cell membrane (plasma membrane: transduction and communication, consists of, phospholipid bilayer, transport proteins, cholesterol, carbohydrates. Membrane proteins: hydrophobic regions in the pm, channel proteins facilitate the movement of ions across pm. Cell structure and function: cytoplasm, semifluid part between cell membrane and nuclear membrane, consists of many enzymes and proteins, cytosol, clear fluid portion of the cytoplasm, nucleus: In most cells: double membrane (nuclear envelope, contains, chromatin, nucleolus; site of rrna production. Endoplasmic reticulum: smooth or agranular er, steroid hormone production and inactivation, site for ca storage in muscles, rough or granular er, ribosomes site for protein synthesis and excretion. Ribosomes: protein + rrna, translation of mrna and protein synthesis. Golgi apparatus: stacked membranes, later stages of protein synthesis. Hlsc 2p09: processes and packages material to be secreted. Peptide synthesis and secretion: rough er: synthesis preprohormone, prohormone, ga: packaging prohormone, hormone, secretory vesicles: storage hormone, secretio(cid:374) hor(cid:373)o(cid:374)e + (cid:862)pro(cid:863) frag(cid:373)e(cid:374)ts.
