Which of the following is not a product of light reaction of photosynthesis?
1 ATP
2 NADH
3 Oxygen
4 NADPH
Explanation:
B During the light reaction process many products are formed i.e., ATP, NADPH, and oxygen, while NADH is formed during respiration. The ATP and NADPH from light-dependent reaction are used to make sugar in the calvin cycle. In another form of light reaction called cyclic photophosphorylation, electrons follow circular path, producing only ATP. Note: Some time student may confused between NADH and NADPH, so NADH is mainly involved in catabolic process while NADPH is involved in anabolic process. NADH is involved in respiration, whereas NADPH is involved in synthesis of carbohydrates.

The products of light reaction during photosynthesis include
1 ATP and NADPH
2 $\mathrm{O}_{2}$ and $\mathrm{NADP}^{+}$
3 $\mathrm{O}_{2}$ and $\mathrm{H}_{2} \mathrm{O}$
A The products of light reaction during photosynthesis include ATP and NADPH. The by product of light reaction in photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) these energy rich molecule are essential for the subsequent dark reaction (Calvin cycle) in production glucose and other carbohydrates.

The microelement, which is an integral part of the electron carrier which transfers electrons for cyt-b-f complex to PS-I is a component of
1 Nitrate reductase
2 Cytochrome- 'C'-oxidase
3 IAA oxidase
4 Dinitrogenase
Explanation:
B - Cytochrome-' $\mathbf{C}$ 'oxidase-Cytochrome $\mathrm{C}$ - Oxidase $(\mathrm{CCO})$ is a respiratory energy- transducing enzyme. It catalyzes electron transfer from cytochrome to molecular oxygen, conserving the released energy as a charge and proton gradient across the membrane in which it is located. - Nitrate reductase: Nitrate reductase is molybdous enzymes that reduce nitrate to nitrite. This reaction is critical for the production of protein in most crop plants, as nitrate is the dominant source of nitrogen in fertilized soils. - IAA oxidase: IAA is the main auxin in plants, regulating, growth and developmental processes such as cell division and elongation. Tissue differentiation, apical dominance, and response to fight gravity and pathogens. - Dinitrogenase : Nitrogenases are enzymes that are produced by certain bacteria, such as cyanobacteria and rhizobacteria. These enzymes are responsible for the reduction of nitrogen to ammonia. Dinitrogenase reductase transfers electrons from and electron donor to dinitrogenase, which can catalyze the reduction of nitrogen to ammonium. Because nitrogen fixation is an energydemanding process, it is tightly regulated in response to several environmental factors.
