NADP - Nicotinamide Adenine Dinucleotide Phosphate is one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules.

NADP+ is the molecule that accepts the electrons given by water. Its reduction by the protein FNR (Ferredoxin NADP+ reductase) gives NADPH,H+.

NADPH,H+ can be used in the Calvin Cycle to reduce 1,3-Biphosphoglycerate (1,3-BPG) into Glyceraldehyde-3-phosphate (G3P), a monosaccharide. It becomes NADP+ again and the cycle keeps repeating as long as the chloroplast receives sufficient and appropriate light.

The    HIV    virus    continuously    invades    and destroys  T-cells  (lymphocytes).  Eventually  the body can't replace the T-cells fast enough, and the  immune  system  deteriorates.  When  the immune  system has deteriorated to the point that it is unable to fight off diseases, a person is diagnosed with AIDS.
