But those long months of cold and darkness are actually a crucial part of the biochemical process that will eventually launch the growth of the embryonic flower bud.

At about this time he started the experiments which helped to prove that nerve and muscle maintain their ionic concentration gradients by a biochemical process known as the sodium pump.

Vision occurs when photons are detected by the retina, initiating a biochemical process affecting the visual pathways and deep structures of the brain.

They are able to communicate to one another through a biochemical process called quorum sensing.

But the biochemical processes by which plants sculpt their many leaf patterns have remained something of a mystery to scientists.
