study guides for every class that actually explain what's on your next test Membrane fusion
from class: Microbiology Definition Membrane fusion is the process by which two lipid bilayers merge to form a single continuous membrane. This is crucial for viral entry into host cells, allowing the viral genome to access the cellular machinery.
congrats on reading the definition of membrane fusion . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Membrane fusion is essential for enveloped viruses to enter host cells. Fusion proteins on the viral envelope facilitate membrane fusion by undergoing conformational changes. pH levels can trigger membrane fusion in some viruses, such as influenza. Membrane fusion can occur at the plasma membrane or within endosomes after endocytosis. Inhibiting membrane fusion is a target for antiviral drugs. Review Questions What role do fusion proteins play in membrane fusion? How does pH influence membrane fusion in certain viruses? Why is membrane fusion important for the viral life cycle?
