anaxon. The nodes contain voltage-sensitive sodium
channels or gates that generate action potentials. The
neural signal jumps from node to node by a process
called saltatory conduction, which creates a faster
transmission than if the action potential traveled the
entire length of the axon.
nomenclature SeeBINOMIAL.
nonclassical isostere SeeBIOISOSTERE.noncompetitive inhibitor An inhibitor that binds to
anenzyme at some location other than the active site
and changes the enzyme’s shape so that it becomes
inactive or less active; binding to a location remote
from the active site and changing its conformation so
that it no longer binds to the substrate.246 nomenclature
