Where do photochemical reactions occur in plants?

In grana or stroma lamellae have stacks of thylakoid where the photosynthetic pigments are located and this photochemical reaction takes place.

What is photochemical in plants?

Plant photochemistry is a highly regulated process, in which the solar energy absorbed as photons by the light-harvesting complexes (LHCs) is transferred to the reaction centres (RCs), where through charge separation the electrons flow from photosystem II (PSII) through cytochrome b6f and diffusible electron carriers …

What is the product of photochemical reaction found in plants?

Through photosynthesis, plants convert the energy of sunlight into stored chemical energy by forming carbohydrates from atmospheric carbon dioxide and water and releasing molecular oxygen as a byproduct. Both carbohydrates and oxygen are needed to sustain animal life. Many other processes in nature are photochemical.

What type of photochemical reaction is photosynthesis?

Ans: Chemical reactions that take place in the presence of light are called photochemical reactions. Photosynthesis is a photochemical reaction in which the leaves of green plants prepare glucose and oxygen from carbon dioxide and water in the presence of chlorophyll and sunlight.

Is photosynthesis a photochemical reaction?

Photosynthesis is a photochemical process by which green plants, seaweeds, algae, and certain bacteria absorb solar energy and utilize it to convert the atmospheric carbon dioxide to carbohydrates in the presence of water.

Why photosynthesis is called photochemical reaction?

Answer. Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. Through photosynthesis, plants convert the energy of sunlight into stored chemical energy by forming carbohydrates from atmospheric carbon dioxide and water and releasing molecular oxygen as a byproduct.

What happen during photochemical reaction of photosynthesis?

Hint: Photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules.

Why photosynthesis is known as photochemical reaction?

Which of the following is a photochemical reaction?

Examples of photochemical reactions Photosynthesis: plants use solar energy to convert carbon dioxide and water into glucose and oxygen. Human formation of vitamin D by exposure to sunlight. Bioluminescence: e.g. In fireflies, an enzyme in the abdomen catalyzes a reaction that produced light.
