Document Summary
The cell is an integrated package so it can stay intact. Doesn"t prevent (completely) traffic of molecules to cross the membrane this where the selectivity comes in. Allow cells to detect and release messages from other cells: 2) around organelles. Prevents molecules inside the organelle from escaping: e. x. Mitochondria there are enzymes for cellular respiration confined within the mitochondria by a membrane which lines the mitochondria. In order to achieve those functions you need a structure that can achieve them. Leaflet they are held together by hydrophilicity, there are no chemical bonds holding it together. It has a soft and floppy assembly and can be easily disruptive they refer to them as fluid membrane. In passing it has a peripheral advantage for the cell of being self- repairing. A) peripheral proteins = extrinsic: can be found on either surface. Allows fast transport of particles.
