why is dark reaction called as biosynthetic phase?

Please find below the solution to the asked query

The dark reaction is also called biosynthetic phase because it involves the synthesis of food (organic compound glucose) from simple inorganic substances. It uses the products of light reaction (ATPs and NADPH) to reduce CO2 into carbohydrate (glucose).

?Chloroplasts allign themselves along the mesophyll walls ?during photosynthesis ?in order to get maximum quantity of incident light.Chloroplasts allign themselves with their flat surfaces perpendicular to walls under ?very high light intensities in order to get only require quantity of incident light.

?

The protons and oxygen formed during spliting of water are released ?in the thylakoid lumen.?

It results in increase in the number of hydrogen protons in the thylakoid space that causes proton gradient. ?Down flow of protons from high to low concentration along gradient through ATPase complex provides the energy that allows an ATP synthase enzyme to produce ATP .

?

Calling biosynthetic phase ?as the dark reaction is a misnomer (a word or term that suggests a meaning that is known to be wrong)?because biosynthetic phase cannot occur for long if light phase is absent. Biosynthetic phase depends on the products of light reaction ATP and NADPH.

?After light becomes unavailable, the biosynthetic process continues for some time, and then stops. If then, light is ?made available, the synthesis starts again.?So, biosynthetic should not be totally considered as the dark reaction.
