Question

photosynthesis is reversible or irreversible reaction? Prove how if it is reversible or irreversible....

Answer 1

$\huge\mathfrak{Answer}$....✍️

Photosynthesis is a process done by green plants for their preparation of food with the help of Water and other minerals from the soil , carbon dioxide from the atmosphere and sunlight from the sun , with all these resources , the green leaves prepare a food called glucose. Hence , formation of glucose is a chemical change , so the process of photosynthesis can not be reversed. So , it's Irreversible.

Answer 2

any, many, chemical reactions can run both directions. So, a typical chemical reaction that takes A and B and produces C:

A + B -> C

Will usually work the other way around; C produces A plus B.

A + B <- C

The overall reaction for photosynthesis looks like this.[1]But it won’t normally run the other way around because photosynthesis is actually a complex series of reactions, [2] each of which would have to operate in reverse. These reactions include the Calvin cycle and the synthesis of carbohydrates. If just one of those steps fails to run in reverse, the whole thing won’t reverse.

But there’s another way to look at this. Photosynthesis takes light and uses it to create sugars. The logical reverse is to take energy in the form of sugar, metabolize it through glycolysis and then the Krebs cycle to generate ATP, which you can then use to produce light. Fireflies do that using a substance called Luciferin.[3]

In that sense, fireflies do the reverse of photosynthesis. They get the energy needed to create light from nutrients they got from plants. Those plants generated those nutrients through photosynthesis.
