ligand-gated channels


a: Ligand-gated channels ~
b: enzymes


"Ligand-gated channels are like enzymes in that they exhibit great specificity in the ligands that they bind. Binding drives the channel into its open state. One channel may be opened by acetylcholine (ACh) and ignore dopamine, whereas another may be opened by dopamine and be totally insensitive to ACh. As a rule, a particular channel type recognizes just one natural ligand."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
