Question
Which statement is false?A. Enveloped viruses and naked viruses both may enter cells using the fusion method.B. Many enveloped viruses enter the cell by receptor-mediated endocytosis.C. Undergoing shape changes and creating channels in the host cell membrane is an alternative method of cell penetration used by naked viruses.D. Naked viruses enter the cell by receptor-mediated endocytosis.
Solution
To determine which statement is false, let's analyze each option:
A. Enveloped viruses and naked viruses both may enter cells using the fusion method. This statement is true. Both enveloped viruses and naked viruses can enter cells using the fusion method, where the viral envelope fuses with the host cell membrane.
B. Many enveloped viruses enter the cell by receptor-mediated endocytosis. This statement is true. Receptor-mediated endocytosis is a common method used by enveloped viruses to enter cells. The virus binds to specific receptors on the cell surface, triggering the internalization of the virus into the cell.
C. Undergoing shape changes and creating channels in the host cell membrane is an alternative method of cell penetration used by naked viruses. This statement is true. Naked viruses can also use an alternative method of cell penetration by undergoing shape changes and creating channels in the host cell membrane. This allows the virus to directly enter the cell without the need for receptor-mediated endocytosis.
D. Naked viruses enter the cell by receptor-mediated endocytosis. This statement is false. Unlike enveloped viruses, naked viruses do not typically enter cells through receptor-mediated endocytosis. They primarily use the alternative method mentioned in option C, by undergoing shape changes and creating channels in the host cell membrane.
Therefore, the false statement is D. Naked viruses enter the cell by receptor-mediated endocytosis.
