@ sakshi
i think u know what is photophoporylation , ryt ??
let me to define that –
Photophosphorylation refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things.
An electron transport chain (ETC) is a series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
In both cases the electron transport chain uses the energy to pump hydrogen ions across a membrane. The protons pass back through ATP synthase, driving the production of ATP. In photosynthesis this ATP is used to construct organic molecules from carbon dioxide and water.
In bacteria, the electron transport chain is located in their cell membrane. In chloroplasts, light drives the conversion of water to oxygen and NADP+ to NADPH with transfer of H+ ions across chloroplast membranes.
and REFER TO THE NCERT TEXTBOOK FOR THE DIAGRAM ,
THE DIAGRAM IS MORE UNDERSTANDABLE THEIR ,
and if u have a trueman , then the concept are even more explained . and if more doubt ,, kindly revert .
ALL THE BEST ..
