The key difference between ATP and NADPH is that the ATP is the energy currency of many of the living organisms while the NADPH is the typical coenzyme used for the reduction reactions of anabolic processes seen in plants.. Adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH) are phosphorylated compounds present in organisms. One molecules of ATP is used in this process. Both components can be easily distinguished by the absorbance maximum of NADPH2 at 340 nm. This conversion occurs during light phase of photosynthesis. The precursor for the pyridine ring (adenine) is quinolinate across all organisms, whereas the nicotinamide comes from vitamin B3. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, a precursor for the synthesis of nucleotides. ATP is converted into ADP and NADPH2 is converted into NADP. NADP + Definition. In order for NADP+ to transform into NADPH, the former requires two electrons and two hydrogen ions. The Photophosphorylation process that results in movement of electrons in a cyclic manner for synthesizing of ATP molecules is referred to […] Steps of the process Step 1: Phosphate is transferred from ATP to glucose, making Glucose-6-phosphate. This generates the ATP and reduced NADP which are used in the light-independent reaction in the stroma. Both NADP and NADPH2 show an absorbance maximum at 260 nm; how-ever, NADPH2 shows an additional peak at 340 nm (fig.1), The first step in this pathway is the rate-limiting conversion of tryptophan to N -formylkinurenine ( N -formylkin) by either IDO or TDO. The first stage is called the light-dependent stage wherein the light energy of the sun is converted into the energy carrier ATP and electron carrier NADPH which carry the energy and free electrons to the next stage. NAD coenzyme plays a crucial role in this. The light dependent reactions are the first of the two stages of photosynthesis and take place on the membranes of the thylakoids as chlorophyll a or other photosynthetic pigment is excited by a photon and the water molecule is split into oxygen, hydrogen ions and free electrons. In order for NADP+ to transform into NADPH, the former requires two electrons and two hydrogen ions. When the two atoms of hydrogen join with NADP, oxygen is liberated, and this is the source of oxygen gas in our atmosphere. Oxidative phosphorylation -During this step, NADPH2 is oxidized to produce ATP molecules. ADP. a) either an oxidation or a reduction. For NAD, the reaction is: This process fundamental to the life of the plant and of vital importance to humans and their health. During the interaction, the electrons change NADP from its oxidized state - NADP + - to its reduced state - NADPH.

It involves a ten step process in which each steps are catalyzed by enzyme. This acid is converted to another 4-C acid, the malic acid which enters into the chloroplasts of bundle sheath cells and there undergoes oxidative decarboxylation yielding pyruvic acid (a 3-C compound) andCO 2.CO 2 released in bundle sheath cells reacts with Ribulose-1,5-biphosphate (RuBP) already present in the chloroplasts of bundle sheath cells and thus Calvin cycle starts from here. Solution : Non cyclic photophosphorylation involved both PS-I and PS-II. Just a few years before Harden and Young’s discovery of NAD, Louis Pasteur had shown that yeast cells were responsible for fermentation, the process in which yeast cells consume sugars … NAD+ has the main job of carrying around electrons for use by the mitochondria and respiration while NADP has a different function. ATP is converted into ADP and NADPH2 is converted into NADP. The NAD + consuming enzymes, PARPs, cleave NAD + into NAM and ADP-ribose (ADPR), as a result generating a chain of ADPR. ◆ NADH is used in cellular respiration, a process in which body cells obtain energy from nutrients. In this, it transports a noncyclic electron. The same is true for its NAD counterparts. Plants primarily use NADPH during photosynthesis to make glucose and oxygen. It is seen from analysis that the compound cannot be exist as NADP in cell. In light reactions two important products (NADPH2 and ATP) are formed. If NAD + is not available, the second half of glycolysis slows down or stops. This process can either be a cyclic process or a noncyclic process. Glucose-6-phosphate is more reactive than glucose. The NADPH first accepts the electrons and hydrogen when special enzymes transfer these particles to the molecule NADP+. Pyruvic acid is converted into oxalacetate that enters Kreb's cycle .
