      I literally have the worst textbook for this in the world and my teacher isnt any help! Somebody help me?

      use of energy, transport proteins

      Wikipedia is pretty good for an introduction to this topic. Chase some hyperlinks.

      Nice surprise about this shorter form. Can you tell us what it is you are talking/writing about?
      Has any info. about this shorter form been posted before (and i just missed it)?

      active transport involves usage of ATP molecules \passive transport does not.
      active transport takes place against conc.gradient\it takes place along the gradient.
      mol. enter through spcl.pore on the cell membrane \mol. enter along with the water flow
      via endosmosis.

      active transport does not have to go against conc. gradient, theoretically.

      In active transport mollecules or ions move from at the region of lower concentration to the region of higher concentration until concentration becomes equal on both sides.This process require energy(ATP).
      In passive transport molecules or ions move at the region of higher concentration to the region of lower concentration until the concentration becomes equal on the both sides.This process does not require energy.

      “active transport does not have to go against conc. gradient, theoretically.”

      My question is related to that:

      In action potential, right after depolarization, does Na+/K+ pump keep moving sodium out and potassium in? Than it would move those ions down their gradient (!?), still at the expense of ATP (!?). Is that true? Would that be an example to the statement above?

      15 Important Difference between Active and Passive Transport
      Active transport involves the movement of molecules against the concentration gradient by use of biochemical energy while passive transport is the movement of molecules along a concentration gradient without using energy.
      Active transport involves the movement of molecules from a region of low concentration to a region of high concentration while passive transport involves the movement of solvent molecules from a region of high to low concentration.
      Active transport tends to be rapid and unidirectional while passive transport tends to be comparatively slow and bidirectional.
      Some of the common materials transported by active transport are large cells, proteins, lipids, and complex sugar ions whereas those of passive transport are water, lipids, carbon dioxide, and oxygen.
