c. disease-causing agent helps pathogen to reproduce & do chemical reactions Activated when surface antibodies bind to pathogen’s antigen proteins that bind to antigens to immobilize pathogen make antibodies cells that quickly begin immune response after antigen is encountered a second time cells that consume (foreign particles, damaged cells) any foreign protein that causes an immune response Releases cytokines to activate B & T cells Quickly kills infected cells
