Question

The products of photochemical reaction are
A. $O_2$, ATP and NADPH
B. $O_2$
C. ATP and NADPH
D. Organic compounds especially carbohydrates.

Answer 1

Hint:In photosynthesis, the energy from the light is converted to ATP and NADPH, which is then used in the dark reaction to create organic compound glucose.

Complete Answer:
The photochemical reaction is none other than a chemical reaction that begins with the absorption of light as a source of energy. Temporary peak states would be activated as the molecules absorb light, and there would be significant variations in physical and chemical properties from the individual molecules. The resulting chemical configurations could be isolated, modified, mixed between identical or different molecules along with the move of hydrogen atoms, the electronic charge to detach molecules, protons, and electrons. The peak states are better reducers and better acids relative to the specific ground states.
Photosynthesis is a photochemical mechanism through which green plants, seaweeds, algae and some bacteria consume solar energy and use it to transform atmospheric carbon dioxide into carbohydrates in the presence of water. Using photosynthesis, plants will transform sunlight energy into the chemical energy being stored and thus form carbohydrates using water and carbon dioxide and release oxygen as a reaction product.Light reaction in photosynthesis occurs in chloroplast membranes by using sunlight and water to create oxygen, ATP and NADPH.The energy from the light is converted to ATP and NADPH, which is then used in the dark reaction to create organic compound glucose, so the organic compound is a byproduct of the dark reaction.

Thus, the correct answer is option A. i.e., $O_2$, ATP and NADPH.

Note: In photosynthesis, light energy is absorbed by chlorophyll found in chloroplast thylakoids in order to create photons that promote the conversion of water and carbon dioxide into sucrose or starch. Photons break water and allow the creation of ATP that drives the entire process.
