WebDopamine. Dopamine belongs to a family of biological compounds called catecholamines (see Figure 1). Dopamine is synthesized from the compound L-dihydroxyphenylalanine (L-dopa) via the enzyme dopa decarboxylase. In noradrenergic neurons and in the adrenal glands, dopamine is the precursor for the neurotransmitter norepinephrine.

WebMar 18, 2024 · neurotransmitter, also called chemical transmitter or chemical messenger, any of a group of chemical agents released by neurons (nerve cells) to stimulate neighbouring neurons or muscle or gland cells, thus allowing impulses to be passed from one cell to the next throughout the nervous system. The following is an overview of … WebCell-cell signaling involves the transmission of a signal from a sending cell to a receiving cell. However, not all sending and receiving cells are next-door neighbors, nor do all cell pairs exchange signals in the same way. There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine ... can shredding be recycled
