Final answer:
The statement is True; constitutive exocytosis is a continuous process in all eukaryotic cells, involving the Golgi apparatus for the secretion of proteins without specific triggers.
Step-by-step explanation:
The statement that the constitutive exocytosis pathway of the Golgi apparatus operates continually in all eukaryotic cells is True. Constitutive exocytosis involves the transport and release of soluble proteins continuously from the cell without the need for a specific trigger or signal. The Golgi apparatus plays a critical role in modifying, sorting, and packaging these proteins into secretory vesicles. Once the vesicles are formed, they move towards and fuse with the plasma membrane, releasing their contents outside the cell.
This process occurs in all types of eukaryotic cells, although the amount of Golgi and the rate of secretion can vary significantly depending on the cell's function. For instance, cells with high secretory activity, such as those in salivary glands or the immune system, have more Golgi and a more active secretory pathway. Additionally, some cells also possess a regulated secretory pathway, which stores and secretes certain substances in response to specific signals.
