Complement Proteins - Innate Inflammatory response

### Innate inflammatory response: heterogenous group of serum proteins that are chemotactic for phagocytes and lytic for bacteria-opsonin

## Step1: Understanding the Concept of Complement Proteins### Complement proteins are a part of the immune system that enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.## Step2: Identifying the Role of Complement Proteins in Innate Inflammatory Response### In the innate inflammatory response, complement proteins act as chemotactic agents for phagocytes. This means they attract phagocytes to the site of infection or injury. They also have lytic properties, meaning they can destroy bacteria.## Step3: Recognizing Complement Proteins as Opsonins### Opsonins are molecules that mark pathogens for destruction by phagocytes. Complement proteins also function as opsonins, enhancing the ability of phagocytes to ingest and destroy pathogens.
