    [1] [2] They can be divided into 7 families of G protein-coupled receptors which activate an intracellular second messenger cascade to produce an excitatory or inhibitory response. The exception to this is the 5-HT 3 receptor which is a ligand-gated ion channel .

    Acidity of diethyl malonate, a 1,3-dicarbonyl compound The central carbon in 1,3-dicarbonyl compound is known as an activated methylene group. This is because, owing to the structure, the carbon is especially acidic and can easily be deprotonated to form a methylene group.

    en.wikipedia.org/wiki/Mitochondrial_shuttle

    The mitochondrial shuttles are biochemical transport systems used to transport reducing agents across the inner mitochondrial membrane. NADH as well as NAD+ cannot cross the membrane, but it can reduce another molecule like FAD and [QH 2] that can cross the membrane, so that its electrons can reach the electron transport chain.

  9. Biomolecular gradient - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_gradient

    In certain organisms, the choice of cell fate can be determined by a gradient, a binary choice, or through a relay of molecules released by a cell. [1] If cell fate is binary, the identity of the cell is influenced by the presence or absence of a signaling molecule; consequently, these signals can also induce cell fate acting in a relay. [1]
