parallel measurements of the release of dopamine beta-hydroxylase ( ec 1.14.17.1 ) ( an enzyme associated with chromaffin granules ) and lactate dehydrogenase ( ec 1.1.1.27 ) ( which is confined to the cytosolic compartment ) suggest that this increase in secretion occurs as a result of an enhanced rate of exocytosis rather than by any other route .
