Question

why is the spatial separation of photosynthesis within the chloroplast important

Answer 1

It is important to have spatial separation of photosynthesis in the chloroplast because in one part of the chloroplast the plants absorb energy from the sunlight, which is then sent to the other part of the chloroplast where the Calvin Cycle occurs and creates glucose to feed the plant.

The ATP and NADPH are used in the light-independent reactions with CO2 to build carbohydrates. Both these processes are spatially separated within the chloroplast, with the light reactions occurring in the thylakoid membrane and the light-independent reactions occurring in the stroma.

Both the processes are separated spatially in the chloroplast because ATP is the light energy which technically powers everything and the NADPH also goes in, but not from the light.

Answer 2

Well, for the plants to make the foods and energy these spatial separation is necessary within the chloroplast. Because   ATP as well as the NADPH used in the absence of  light with the help of the carbondioxide . While the energy absorption process from the sunlight sent to the choloroplast in order to start the calvin cycle. These light dependence reaction occurs in the tylakoid membrane while on the other hand the reaction without light occurs in the stroma of choloroplast. Both of these reaction needs separation because of the energy formation process are different in them.
