NADPH is reduced NADP (Nicotinamide adenine dinucleotide phosphate) and is used as a reducing agent. NADPH oxidises to form NADP. In plants, NADP is reduced in the last step of the electron chain of the light reactions of photosynthesis.The NADPH produced is then used as a reducing agent in the Calvin cycle of photosynthesis. NADPH is used in catabolic processes.n plants, NADP is reduced in the last step of the electron chain of the light reactions of photosynthesis.

Your A+ Blood is Important. Home > About Blood > Blood Education > Blood Types > Your A+ Blood is Important. As an A Positive donor you are incredibly important to maintaining the blood supply in our community. A Positive is the second most common blood type and therefore just as many patients need this blood type. Annually, more than 120,000 units of blood, platelets and plasma are required to meet the needs of the hospitals we serve, and your blood type is crucial to maintaining an adequate supply.
A positive blood group means that the person has Rh antigen on the red blood cells whereas a negative blood group means that the Rh antigen is absent on the red blood cells. Unlike ABO system, an Rh-ve person will not have anti-Rh antibody in the blood unless he/she has been previously exposed to Rh +ve blood.-negative blood group is the  universal donor  blood group. This means that a person with any blood group can receive O-negative blood. This is very important in emergency situations when a person requires immediate blood transfusion and there is no time to test his/her blood group.
