Document Summary
Biology chapter 5- membranes and transport (lecture 2-3) The proteins found on one half of the bilayer are structurally and functionally distinct from those of the other half. A- it is the idea that the two halves of the lipid bilayer are not identical. Each half contains a different size and number of proteins in the lipid. Q- why is maintaining proper membrane fluidity important for membrane. A- because without the proper fluidity normal membrane permeability. Can be inhibited, as well as causing enzymes and other proteins in the. If the membrane solidifies, the e. t. c ceases to operate. If the membrane is too fluid, this can lead to membrane leakage. Membrane structure according to the fluid mosaic model, in which integral proteins are suspended individually in a fluid lipid bilayer. Peripheral proteins are attached to integral proteins or membrane lipids mostly on the cytoplasmic side of the membrane.
