The classical complement pathway is a group of proteins that arrange the antibody response when you are sick. So basically they will spring into action when something is not right in your body.

Which complement protein is the key to activating the alternative pathway of complement activation?
C3
What does complement proteins do?
Complement is part of the innate immune system (one you are born with). It consists of small protein molecules that circulate in the blood stream. Complement has three pathways, The classic pathway; The alternative pathway; and the lectin pathway. In the classical pathway, complement is activated by triggers such as the binding of an antigen to an antibody. In the alternative pathway, Complement is part of the natural immune system and complement assist in the opsonization, or the marking of an antigen to be destroyed by a phagocyte. This like the antigen has been marked with black marker so that a killer cell (phagocyte-cell eater) can find it to eat it. Finally the lectin pathway, which is similar to the classical pathway in terms of structure but this pathway starts with lectin or ficolin binding to sugars. After activation complement can trigger any number of events such as opsonization, chemotaxis, inflammation, and lysis (breaking) of cells.
The lectin pathway for complement action is initiated by?
mannose on the parasite
What is a mechanism of nonspecific resistance?
activation of the complement via the alternative pathway
Does C2a or C2b bind C4b in classical pathway of complement activation?
C2a
Why is the alternative pathway of complement useful in the early stages of an infection?
It does not rely on activation by antibodies.
What are compliment proteins?
The complement system is a group of small proteins helps or complent the antibodies or phagocytic cells to clear the pathogens. These small proteins generally circulating in blood plasma as an inactive form. complements are regulated by complement control proteins. complement caascade pathway activates various complement proteins.

What is the purpose of the lytic pathway?
Viral reproduction. See more in the related questions below.
How does the innate immune system interact with the adaptive immune system?
The complement system is a series of about 20 proteins that are involved in a cascade effect during an immune response. Complement is generally divided up into 3 pathways: classical, lectin, alternate. The classical pathway involves a complement protein binding to an antigen-antibody complex (and thus its role in adaptive immunity). Whereas in the alternate pathway, complement (C3) binds directly to the foreign cell( usaully bacteria). Thus its repsonse is non specific and therefore is also part of the innate imune system.
