They both help to transfer or get rid of electrons produced during cellular metabolism.
NAD+, (or nicotinamide adenine dinucleotide)
NADP is part of the Light Independant reaction (Calvin Cycle) of photosynthesis. The NADP combines with a Hydrogen Ion to create NADPH.When the NADP is turned into NADPH it basically is just an energy carrier to turn CO2 into Carbon based sugar molecules.
Inside the cell, NAD is mostly oxidized. The ready availability of the NAD+ will help to speed up the oxidative reactions in the TCA and glycolysis. In contrast, NADP is mainly found in the reduced state. The high level of NADPH will promote reductive reactions in biosynthesis. (http://watcut.uwaterloo.ca/webnotes/Metabolism/page-8.2.html) NAD+ is reduced to NADH in respiration, and NADPH is produced from NADP+ in the light stage of photosynthesis and is not involved in respiration. Remember P (NADP+ and Photosynthesis).
Electrons are crucial in cellular respiration and photosynthesis as they facilitate energy transfer through redox reactions. In cellular respiration, NAD+ accepts electrons during the breakdown of glucose, becoming NADH, which then donates electrons to the electron transport chain to produce ATP. Similarly, in photosynthesis, NADP+ accepts electrons during the light-dependent reactions, forming NADPH, which provides the reducing power for the Calvin cycle to synthesize glucose. Both processes rely on these electron carriers to efficiently convert energy from one form to another.
Without NAD+ in glycolysis, the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate cannot occur, halting the production of ATP. As a result, glycolysis is inhibited, and the cell's ability to generate energy through this pathway is compromised.
Both NAD+ and NADP+ are coenzymes involved in redox reactions in cells. They both act as electron carriers, accepting and donating electrons during metabolic processes. NAD+ is primarily involved in catabolic reactions, while NADP+ is involved in anabolic reactions.
GOGAT may have not a same affinity for NADP and NAD. GOGAT depednance for NADP or NAD is related to the analysed tissu (bacteria, fungi, plant...) [floristqiue@yahoo.fr] GOGAT may have not a same affinity for NADP and NAD.
NAD+, (or nicotinamide adenine dinucleotide)
like NADP+ in photosynythesis, each NAD+ accepts a pair of high-energy electrons. This molecule, known as NADH, holds the electrons until they can be transferred to other molecules. By doing this, NAD+ helps to pass energy from glucose to other pathways in the cell.

it serves as coenzyme for many enzymes in the form of NAD,NADP,NADPH..............
Coenzyme, like NAD, NADP, CoA.
In Photosynthesis, in Non- Cyclic Photophosphorylation, NADP- is produced but is then reduced to NADPH2 which is a reduced coenzyme. The reactions to get from NADP- to NADPH2 are shown below:NADP- + H+ ---> NADPH (The H+ came from the hydrolysed water molecule from PSII)NADPH + e- ---> NADPH-NADPH- + H+ ---> NADPH2

NADP (nicotinamide adenine dinucleotide phosphate) is a coenzyme that plays a vital role in cellular energy transfer processes, specifically in photosynthesis. It acts as an electron carrier, helping to transfer electrons and store energy in the form of an electrochemical gradient. While NADP itself is not a direct source of energy, it is essential for the conversion of light energy into chemical energy in plants.
