Document Summary

Label the blank diagram of the cell from lecture 1 as much as possible using lecture notes and your own research. Protein will be produced by ribosomes bound to the rough er. Describe the cytoskeletal elements and what roles they play. Microtubules hollow tubes of tubulin and highway for motor proteins (dyneins) And combine to make dimers connect w/ other dimers to make columns: maintain cell shape & cell motility (organelle movement) have polarity and grow on (+) distal end. Microfilaments 2 strands of actin subunit wrapped in loose spiral: maintain cell shape (membrane, muscle contraction, cell division, have weaker motor proteins (myosin) that generate power stroke to move things. Intermediate filaments fibrous proteins supercoiled into thick cables: cell shape, anchorage of nucleus and organelles. Signal transduction pathways serve a number of specific functions. Describe the problems associated with signal transduction, the advantages, and the problems that the transduction we"ve discussed overcome. (timecourse of signal, amplification, etc )
