Document Summary
Slide 2: a cell is an environment by itself, as a cell, there is an internal environment, any environment has to be contained, in the cell it is the cell membrane. Slide 3: the cell is contained within a cell membrane, cell membrane with the interaction with the cytoskeleton and the actin filaments, the underneath. Smooth er: fat metabolism, muscle contraction, rich with calcium, mitochondria. Integral protein has at least one trans-membrane domain. Sometimes the cell has to be more rigid, sometimes it depends on the tissue we are looking at. Slide 5: this protein has 3 trans-membrane domains. Some of the glucotransporter (located within the bilayer and has 12 domains) Slide 6: permeable is able to permit this specific molecule, non-permeable, no way membrane will transmit this structure, either membrane is permeable or impermeable. If the membrane is permeable, it can be passive or active: a(cid:374)(cid:455)thi(cid:374)g passi(cid:448)e does(cid:374)"t (cid:396)e(cid:395)ui(cid:396)e e(cid:374)e(cid:396)g(cid:455, active membranes require atp.
