The type of immunity that provides lifetime immunity for the body against a specific pathogen is called acquired immunity. It is also referred to as adaptive or specific immunity.
Acquired immunity is not present at birth. it is learned. As a person's immune system encounters foreign substances (antigens) the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its uniqueness lies in its ability to learn, adapt and remember.
Acquired immunity takes time to develop after first exposure to a new antigen. However afterward, the antigen is remembered, and subsequent responses to that antigen are quicker and more effective than those that occurred after first exposure. Memory of a particular antigen is kept by the B and T lymphocytes.
The electron transport system in the light dependent reaction of photosynthesis is the one that is responsible for the production of electrons that are used as precursor for NADPH production. The NADPH and the other products that are made during the light dependent reaction are used during the dark reaction to produce sugar molecules. So, if the electron transport is disabled, glucose molecule will not be produced during the dark reaction.<span />
