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). Each serving of fries contains 500 Calories.
Bioflix Activity: Membrane Transport -- Vocabulary Review Other factors being equal, a stronger concentration gradient (larger concentration difference between regions) results in faster diffusion.
