Concept explainers
a.
To determine:
The location of the membrane attack complex in gram-negative and gram-positive bacteria.
Introduction:
A group of proteins can work in several pathways to kill the invading pathogen. The end product of the “complement system” is a membrane attack complex. This defense system is called a nonspecific defense because there is no specificity between the pathogen and the serum proteins of the complement system.
b.
To determine:
Gram-positive and gram-negative bacteria, which are more resistance to the formation of membrane attack complex.
Introduction:
The complement system is a very important part of the immune system that enhances the ability of antibodies and phagocytic cells to inhibit the growth of microbes and damaged cells from an organism and attacks the pathogen's cell membrane.
