The seminal vesicles contribute up to 85% of the seminal fluid, with the prostate gland secreting the majority of the rest. The seminal vesicles secrete a yellow, alkaline and viscous fluid that contains fructose, fibrinogen, prostaglandins and vitamin C, as well as other specific proteins.
Overview: There are two different secretory pathways, the Regulated Pathway and the Constitutive Pathway. In the regulated pathway proteins are consolidated into vesicles that are stored in the cell until they are secreted in response to a specific signal. In the constitutive pathway vesicles continuously form and carry proteins fron the Golgi to the cell surface.
