The ion which is entering axon terminal A is called Ca²⁺.
The effect which it has is, it causes the release of neurotransmitter from the axon terminal.
Axon terminal is termed as distal termination of telodendria of an axon. Another name for the axon terminal is synaptic boutons. Axon is a long, slender projection which is of a nerve cell.
Their work is to conduct electrical impulses which are referred to as action potential which is a way of neurons of the cell body. Neurons use electrochemical signals and also a neurotransmitter chemical which transmits impulses from one neuron to another.
Axon terminals are being separated from neighboring neurons by a gap known as a synapse. Both the axon terminal and neuron they come from a point which is called the presynaptic neuron.
<span>Each genus contains one or more species. There are 8 main taxonomic groups in biological classification. These are, from the most inclusive to the least inclusive: domain, kingdom, phylum, class, order, family, genus and species. Therefore, each genus contains one or more species.</span>
<span>Enzymes are Biological Catalysts. They increase the rate of Metabolic reactions. Almost all Biological Reactions involve Enzymes. All enzymes are Globular Proteins with a specific Tertiary Shape. They are usually specific to only one reaction.</span><span>The part of the Enzyme that acts a Catalyst is called the Active Site. The rest of the Enzyme is much larger and is involved in maintaining the specific shape of of the Enzyme.</span><span>When a reaction involving an Enzyme occurs, a Substrate is turned into a Product. The Substrate can be one or more molecules. The Active Site of an Enzyme is Complementary to the Substrate it catalyses.</span>
