Document Summary
Gel and fluid forms of the phospholipid bilayer: Gel like consistency --> heat --> fluid-like consistency. High density lipids which are unsaturated hydrocarbons put kinks in the structure which doesn"t permit easy clustering --> lower melting point --> less thermal energy is required to reach membrane fluidity vs saturated chains. Antarctic fish --> highest percentage of unsaturated fatty acid. Thermophilic bacterium --> least percentage of unsaturated fatty acids because it needs saturated fatty acids in order to maintain the protein complexes. A difference in concentrations between solutions --> diffusion of particles until the concentrations are equaled out. No, it only develops if we are moving water around. Order the following molecules with respect to their ability to cross a pure lipid membrane: We can draw the line between water and glucose as to what can actually pass the membrane or not. How can we analyze this question in terms of relevance/importance:
