Final answer:
Wnt11, dsh (Dishevelled), and GBP (G protein) are proteins involved in the Wnt signaling pathway and are typically released from secretory vesicles that fuse with the plasma membrane. These vesicles are created in the Golgi apparatus after the proteins have been modified and tagged. They are important for intercellular communication and development.
Step-by-step explanation:
Wnt signaling is a complex process involved in embryonic development and various other cell processes. Proteins like Wnt11, dsh (Dishevelled), and GBP (G protein) play a role in this pathway. These proteins are typically processed through the endomembrane system of a cell, which includes the endoplasmic reticulum and the Golgi apparatus.
Once proteins are modified and tagged inside the cell, they are encased into vesicles that bud off from the Golgi apparatus. There are two types of vesicles that can form: transport vesicles, which deliver their contents to various intracellular locales, and secretory vesicles, which fuse with the plasma membrane and release their contents outside the cell.
Proteins like Wnt11 are packaged into secretory vesicles following their modification in the Golgi. Subsequently, these vesicles travel to the plasma membrane, fuse with it, and release proteins like Wnt11, dsh, and GBP into the extracellular space. This release can have different purposes, including the activation of signaling pathways that communicate with other cells or the organism's external environment.
