Here is chemistry in action. This article describes and summarizes the functions of organs- many are driven by underlying chemical gradients. The picture shows a plant and its functions (driven by a membrane chemical process shown) and a neuron- a basic component of an animal brain. Chemicals are not shown for delivery of messages on an axon, however, they are implied by the word “action potential” which implies an electrical process of some kind.
Chemistry is critical for the functioning of all living creatures.
