Here's why:
* Immune Response is Complex: The human body's defense against viruses involves a complex network of cells, proteins, and processes.
* Multiple Players: While enzymes play a crucial role, they are not the primary "repel" force.
* Specific Defenses: The body uses a variety of mechanisms to target viruses, such as:
* Antibodies: These proteins bind to viruses, preventing them from attaching to and entering cells.
* Interferons: These signaling molecules alert nearby cells to the viral threat and activate antiviral defenses.
* Natural Killer Cells: These immune cells destroy virus-infected cells.
* T Cells: These cells are responsible for recognizing and destroying virus-infected cells.
Enzymes in Immune Response:
* Lysozymes: These enzymes are found in tears, saliva, and other bodily fluids. They can break down the cell walls of some bacteria, but they don't directly target viruses.
* Proteases: These enzymes can break down viral proteins, but they are often involved in other immune processes, like the activation of immune cells.
In summary: It's not accurate to say that a single enzyme "repels" viruses. The immune response is a complex and coordinated effort involving various cells, proteins, and enzymes.
