\"Select the statements that are INCORRECT, and for each incorrect statement EXPLAIN why!! (slightly modified 12-10) a) The plasma membrane is highly impermeable to all charged molecules. b) Channels must first bind to solute molecules before they can select those that they allow to pass. c) Transporters allow solutes to cross a membrane at much faster rates than do channels. d) Certain H+ pumps are fueled by light energy. e) The plasma membrane of many animal cells contains open K+ channels, yet the K+ concentration in the cytosol is much higher than outside the cell. f) A symport would function as an antiport if its orientation in the membrane were reversed (i.e., if the portion of the molecule normally exposed to the cytosol faced the outside of the cell instead). g) The membrane potential of an axon temporarily becomes more negative when an action potential excites it.\"

Solution

All the statements are true actually.

As it\'s given only to select the incorrect ones, no point is incorrect here.
