The motion of an individual dye moleculeis random whether or not a concentration gradient is The discs and tubules of the ER are hollow, and the space inside is called the lumen. Cellular respiration breaks down sugar, and combustion breaks down octane. Certain molecules use facilitated diffusion to cross the plasma membrane. This means that ions like sodium, potassium, calcium, and chloride cannot cross membranes to any significant degree by simple diffusion, and must instead be transported by specialized proteins (which well discuss later). This is an example of, The plasma membrane forms a pocket that pinches inward, forming a vesicle that contains material from outside the cell. Energy is conserved.
