When overcharged at low rates, oxygen produced at the positive electrode passes through the separator and recombines at the surface of the negative.

When Scheele discovered oxygen he called it " fire air " because it supported combustion, but he explained oxygen using phlogistical terms because he did not believe that his discovery disproved the phlogiston theory.

When silicone is burned in air or oxygen, it forms solid silica ( silicon dioxide ) as a white powder, char, and various gases.

Neurons generate electrical signals that travel along their axon s. When a pulse of electricity reaches a junction called a synapse, it causes a neurotransmitter chemical to be released, which binds to receptors on other cells and thereby alters their electrical activity.

When a ligand binds to the GPCR it causes a conformational change in the GPCR, which allows it to act as a guanine nucleotide exchange factor ( GEF ).

When it is present at a much higher concentration, it also binds to OR3, inhibiting transcription from P < sub > RM </ sub >, thus regulating its own levels in a negative feedback loop.

When a court binds itself, this application of the doctrine of precedent is sometimes called horizontal stare decisis.

When pulled tighter, the rope passing over itself binds it in place.

When released, ADH binds to V2 G-protein coupled receptors within the distal convoluted tubules, increasing cyclic AMP, which couples with protein kinase A, stimulating translocation of the aquaporin 2 channel stored in the cytoplasm of the distal convoluted tubules and collecting ducts into the apical membrane.

When a ligand binds to a G protein-coupled receptor ( GPCR ) that is coupled to a Gq heterotrimeric G protein, the α-subunit of Gq can bind to and induce activity in the PLC isozyme PLC-β, which results in the cleavage of PIP < sub > 2 </ sub > into IP < sub > 3 </ sub > and DAG.

When the foreign insulin binds with the antibodies, it does cannot work as intended.

When such a conflict arises, all Superior Courts have the discretion to choose which rule they like until the California Supreme Court grants review and creates a single rule that binds all courts statewide.

When it is a player's turn to act, the first verbal declaration or action he takes binds him to his choice of action ; this rule prevents a player from changing his action after seeing how other players react to his initial, verbal action.

When adrenocorticotropic hormone reaches and binds to its target, the adrenal gland, the adrenal gland in turn releases the final key messenger in the cascade, cortisol.

When these residues are phosphorylated, the CTD binds to various protein factors that promote transcript maturation and modification.

When the inducer binds the receptor, it activates transcription of certain genes, including those for inducer synthesis.

When a peptide hormone binds to receptors on the surface of the cell, a second messenger appears in the cytoplasm, which triggers intracellular responses.

When an aminoacyl-tRNA initially binds to its corresponding codon on the mRNA, it is in the A site.

When bird chicks ingest melatonin-rich plant feed, such as rice, the melatonin binds to melatonin receptors in their brains.
