  1. NADPH Nicotinamide adenine dinucleotide phosphate By Tommy Handoko

  2. Chemical Formula of NADPH NADPH (Nicotinamide adenine dinucleotide phosphate) C21H30N7O17P3

  4. Role in Photosynthesis Produced during the Light Reaction (light-dependent reaction) Used in the Calvin Cycle (Dark reaction/light-independent reaction) NADPH is used to produce Glyceraldehyde 3-Phosphate (G3P) which will then become glucose.

  5. Involved in Photosynthesis Light Reaction NADP+ (An electron accepter) Stored energized electrons from the light reaction in for later use in the Calvin Cycle. (‘Reducing power’) Also takes in a Hydrogen ion (H+) hence becoming NADPH from NADP+

  6. Involved in Photosynthesis Calvin Cycle (Dark Reaction) RibuloseBiphosphate + CO2 Produces Biphosphoglycerate(intermediate) ATP then adds a Phosphate compound Becomes ADP NADPH reduces it with the 2 stored Electrons and the Hydrogen ion causing it to lose a phosphate group. Produces Glyceraldehyde 3-phosphate (G3P) This then becomes Glucose

  7. Why is NADPH important? NADPH is essential in producing glucose for the survival of plants Because ATP alone is not enough to produce sugars and complete the Calvin cycle Without NADPH plants would eventually wither and die out No more food chain if plants are not able to survive
