Document Summary
Er plus golgi also required in the chlamydomonas cell. Membrane is not just lipid, more than 50% of the membrane can be protein. The lipid represents the backbone on which the proteins are found. Important that the lipid backbone stays fluid, because things have to move through the membrane. Fatty acids are in a highly saturated state (stiff, more solid) or they in an unsaturated state (making it more fluid) Desaturases differ to the position between which carbons those double bonds are made. Acyl carrier protein binds to fatty acid and then brings it to the enzyme. Whatever two carbons fall beside the catalysis site is where the double bond will be placed. Physiologic importance of unsaturation through the membrane through diffusion, occurs very quickly. Organisms who live in different environments have to deal with a changing temp and therefore an alteration to the fluidity of the membrane. Overtime, and a decreasing temp, the amount of desaturase also decreases.
