Evaluate the following statements about the functional structure of cell membranes. A. All body cells have an unequal distribution of charged ions on the inside and outside of the membranes TRUE/FALSE B. Molecules that are small enough and soluble in lipids can easily diffuse across the cell membrane TRUE/FALSE C. Immune cells take up bacteria and cellular debris directly into the cytoplasm using membrane 'pseudopodia' in order to destroy them TRUE/FALSE D. When channels for a particular ion are opened the ion is able only to go in or out of the cell membrane in the direction of the chemical concentration gradient TRUE/FALSE E. The resting membrane potential can be determined by using the Nernst equation for Ca2+ distribution TRUE/FALSE
