Electrochemical gradients and the membrane potential primary and secondary active transport na+/k+ pump.
Biology4kidscom this tutorial introduces active transport in cells other sections include plants, animal systems, vertebrates, and microorganisms. Active transport sometimes organisms require certain substances and therefore need to move dissolved substances from a region of low concentration to a region where. Two examples of active transport include the root hair cells in plants taking in mineral ions and humans taking in glucose through their intestines in general terms. Passive transport is a type of cellular transport where substances move along the concentration gradient since it is associated with downhill movement of substances.
