Please give the reactions of dark phase of photosynthesis according to this scope of syllabus

Dear student 
Please find your answer below to the asked query 

Its mentioned in your syllabus that detailed equation is not required. 

The process of photosynthesis occurs in two phases – the light reactions and the dark reactions.

Light reactions – As the name suggests, this reaction takes place in the presence of light. Light energy is absorbed by chlorophyll molecules and is utilized for splitting water molecules into hydrogen and oxygen. Additionally in this phase, assimilatory power in the form of ATP and NADPH2 are produced.

Light reactions occur in the membranes of thylakoids.

Events occurring during light reactions:

  • Absorption of light energy by chlorophyll molecules
  • Splitting of water molecules into hydrogen and oxygen atoms
  • Formation of ATP and NADPH2

Dark reactions – This reaction does not require direct light and occurs in the stroma of chloroplasts. During this phase, ATP and NADPH2 (formed during light reactions) are utilized for the reduction of CO2 to carbohydrates (food).

Event occurring during dark reaction:

Reduction of CO2 to form carbohydrates
