many
five
Transcript text: Activation of complement proteins lead to $\qquad$ protective outcomes.
lysis
three
many
five
Solution
The answer is the third one: many.
Explanation for each option:
Lysis: This is a specific outcome of complement activation, where the membrane attack complex (MAC) forms and leads to the destruction of pathogens by creating pores in their membranes. However, it is not the only outcome.
Three: This is incorrect because the number of protective outcomes is not limited to three.
Many: This is correct because the activation of complement proteins leads to various protective outcomes, including opsonization (marking pathogens for phagocytosis), chemotaxis (attracting immune cells to the site of infection), and lysis (destruction of pathogens).
Five: This is incorrect because the number of protective outcomes is not specifically five.
Summary:
The activation of complement proteins leads to many protective outcomes.
