If you ate two slices of pepperoni pizza and wish to burn off all the calories, how long would you have to ride your bike to achieve that? Certain molecules cross the plasma membrane through the process of active transport. 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). Enzymes speed up chemical reactions by lowering the activation energy, which allows the reaction to proceed much more quickly.

For every orange dye molecule that moves from side A to side B, another orange dye molecule moves from side B to side A. I don't think there is a general rule (leaning toward facilitated but I have counter examples too). Part B Materials can be exported in vesicles that fuse with the plasma membrane and release their contents outside the cell. The lipid bilayer is essentially impermeable to solutes that are charged. the cell is engulfing a large particle, the cell is engulfing extracellular fluid, Part C proteins.
