Question

Chemical reaction takes place during dark reaction of photosynthesis is
(A) photolysis
(B) hydrolysis
(C) carbon dioxide is bonded with RUBP
(D) nitrogen fixation​

Answer 1

Answer:

The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma of the chloroplast. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.

Answer 2

C option is the correct answer.

Carbon dioxide is bonded with RuBP.

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.
