A concentration gradient occurs where the concentration of something changes over a certain distance. For example, a few drops of food dye in a glass of water diffuse along the concentration gradient, from where the dye exists in its highest concentration (for instance, the brightest blue or red) to where it occurs in its lowest concentration (the water is still clear).

Figure 1. You have already learned that a covalent bond forms when electrons are shared between atoms. A coordinate-covalent bond (represented by a green arrow in this diagram) forms when both of the shared electrons come from the same atom, called the donor atom (blue). An anion or molecule containing the donor atom is known as a ligand.

A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments, and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases).The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport.

Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis.Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer.
