Question

Explain photo-chemical phase of photosynthesis. Where does it take place?

Answer 1

A photochemical reaction is a chemical reaction induced when a substance's molecules consume mild energy. It happens to place the stacks of Thylakoid.

Complete answer:
Photochemical reaction, a chemical reaction induced in the presence of mild with the aid of the absorption of radiation. The impact of the absorbing mild molecules is the formation of transient excited states whose bodily and chemical aspects vary substantially from the unique molecules.

Photochemical reaction is a chemical reaction in flora the place mild in the structure of strength is fed on and electrons emitted are used to generate electricity and perform a number functions. In grana or stroma lamellae have stacks of thylakoid the place the photosynthetic pigments are positioned and this photochemical response takes place.
The electricity that is released by way of the light response goes to a stroma area where carbon is found, then it will fix the carbon and make contributions to glucose production.

Thus, the required answer is Grana lamellae and stroma lamellae of chloroplast.

In the photochemical phase two photosystems work namely photosystem -1 and photosystem-2 those have different absorption peaks one at 680nm and other at 700nm.

Note: Photochemistry is a branch of chemistry that primarily deals with the response fees and approaches bobbing up from reactant publicity to mild radiation. The photochemical response is really the thermal response of the molecule's electronically excited state, whilst the thermal reaction of the floor kingdom is the darkish response of the molecule.
