What is the function of hemagglutinin in the influenza virus?
A
Hemagglutinin is the name of the reverse transcriptase enzyme in the influenza virus.
B
Hemagglutinin helps release new viruses from infected cells.
C
Hemagglutinin is part of the protein capsid of the influenza virus.
D
Hemagglutinin is involved in assembling the membrane envelope that the virus uses as a cloak when it leaves an infected cell.
E
Hemagglutinin is the protein that helps the influenza virus attach to host cells.
Verified step by step guidance1
Understand that hemagglutinin is a glycoprotein found on the surface of the influenza virus.
Recognize that the primary function of hemagglutinin is to facilitate the attachment of the virus to the host cell. This is crucial for the virus to initiate infection.
Hemagglutinin binds to sialic acid receptors on the surface of the host cell, which allows the virus to enter the cell.
Differentiate hemagglutinin from other viral proteins, such as neuraminidase, which is involved in the release of new viral particles from the host cell.
Clarify that hemagglutinin is not involved in reverse transcription, capsid formation, or membrane envelope assembly, which are functions associated with other viral components or types of viruses.
