Answer:
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. Without amino acids, plants cannot make the special proteins that the plant cells need to grow. Without enough nitrogen, plant growth is affected negatively.

The complement system is a major component of the innate immune response. This system is composed of plasma proteins synthesized mainly by the liver or membrane proteins that are capable of promoting inflammatory responses.
- The COMPLEMENT SYSTEM is a part of the innate immune response that is INVOLVED in neuromyelitis Optica (NMO).
- NMO is an autoimmune inflammatory disease that affects the central nervous system by producing medullary/optical nerve damage, thereby triggering paralysis and/or blindness.
- Aquaporin-4 (AQP4) is an aquaporin (water channel) integral membrane protein which is strongly expressed in astrocytes of the central nervous system.
- This disease (NMO) is caused by aquaporin-4-specific autoantibodies that activate classical complement cascade and astrocytic damage.
