Final answer:
T-SNARE and V-SNARE proteins are the proteins that bring vesicles and target membranes close enough to fuse. The proteins responsible for bringing vesicles and target membranes together for fusion are SNARE proteins, with V-SNAREs on vesicles binding to T-SNAREs on target membranes.
Step-by-step explanation:
The proteins that bring vesicles and target membranes close enough so that they can fuse are T-SNARE proteins and V-SNARE proteins. When V-SNARE proteins on vesicles bind to complementary T-SNARE proteins on target membranes, the membranes fuse.
The proteins responsible for bringing vesicles and target membranes together for fusion are SNARE proteins, with V-SNAREs on vesicles binding to T-SNAREs on target membranes.
The proteins that bring vesicles and target membranes close enough so that they can fuse are known as SNARE proteins. Specifically, V-SNARE (vesicle-SNARE) proteins on the vesicles bind to complementary T-SNARE (target-SNARE) proteins on receiving membranes to mediate the fusion process. This mechanism ensures that vesicles are directed to their correct destinations within the cell, such as the plasma membrane or other organelles. It is critical for the proper sorting and delivery of proteins and lipids that the vesicles contain. The proteins that bring vesicles and target membranes close enough so that they can fuse are T-SNARE proteins and V-SNARE proteins. When V-SNARE proteins on vesicles bind to complementary T-SNARE proteins on target membranes, the membranes fuse.
