Final answer:
The complementary SNARE proteins ensure the fusion of membranes in cellular processes, facilitating intracellular transport and neurotransmitter release. V-SNARE proteins on vesicles bind to T-SNARE proteins on target membranes to enable membrane fusion.
Step-by-step explanation:
Complementary snare proteins ensure the fusion of membranes in cellular processes. SNARE proteins are involved in vesicle trafficking and membrane fusion.
When V-SNARE proteins on the vesicles bind to complementary T-SNARE proteins on the target membranes, the membranes fuse together, allowing the transfer of cargo. This process is essential for intracellular transport, neurotransmitter release, and other cellular activities.
Examples of complementary SNARE protein pairs include VAMP/Synaptobrevin (V-SNARE) and SNAP25/Syntaxin (T-SNARE) in neuronal exocytosis.
