WebThe membranes also have large proteins that are embedded within the lipid bilayer. The proteins often form pores through which water and small, dissolved molecules or solutes can move (Figure 1.5). Ethanol is small (its molecular weight is 46 g/mole or 46 Daltons) and polar, so it has no trouble crossing these cell membranes. howeth road bournemouthWebcell membrane. membrane surrounding all animal cells, composed of a lipid bilayer interspersed with various molecules; also known as plasma membrane. channel protein. membrane-spanning protein that has an inner pore which allows the passage of one or more substances. concentration gradient. hideaway year around campgroundWebOct 13, 2015 · It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). … howeth road evangelical church bournemouthWeb9) Which of the following statements best explains the reason that lipids and proteins are free to move laterally in membranes?
