    GO:0060081    membrane hyperpolarization    The process in which membrane potential increases with respect to its steady-state potential, usually from negative potential to a more negative potential. For example, during the repolarization phase of an action potential the membrane potential often becomes more negative or hyperpolarized before returning to the steady-state resting potential.
    GO:1902161    positive regulation of cyclic nucleotide-gated ion channel activity    Any process that activates or increases the frequency, rate or extent of cyclic nucleotide-gated ion channel activity.

    GO:0007585    respiratory gaseous exchange    The process of gaseous exchange between an organism and its environment. In plants, microorganisms, and many small animals, air or water makes direct contact with the organism's cells or tissue fluids, and the processes of diffusion supply the organism with dioxygen (O2) and remove carbon dioxide (CO2). In larger animals the efficiency of gaseous exchange is improved by specialized respiratory organs, such as lungs and gills, which are ventilated by breathing mechanisms.
    GO:0048240    sperm capacitation    A process required for sperm to reach fertilization competence. Sperm undergo an incompletely understood series of morphological and molecular maturational processes, termed capacitation, involving, among other processes, protein tyrosine phosphorylation and increased intracellular calcium.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
