Kinetic energy is energy in motion. The opening and closing of these channels, and the resulting shifts in ion levels inside the cell, play an important role in electrical transmission along membranes (in nerve cells) and in muscle contraction (in muscle cells). Polar molecules can easily interact with the outer face of the membrane, where the negatively charged head groups are found, but they have difficulty passing through its hydrophobic core. ", Part B Note that the order of the answer options does not match the online version of the quiz. *the kinetic energy of the reactants is less than that of the products There is no movement of orange or purple dye molecules from one side to the other. Why does the reporter have a tube up his nose? Thus, in a single cell, there can be different rates and directions of diffusion for different molecules. Active Transport*. 2Relationship of structure to function Hint 3. D e compustion Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
