• It occurs in matrix of chloroplasts
• This phase donot require light
• It is influenced by temperature
• It consumes NADPH and ATP
• Glucose is the end product

Answer 2

Hey!

In the dark reaction of photosynthesis, the ATP and NADPH formed in the light reaction are used to transform inorganic carbon dioxide (CO2) into organic carbon compounds, a process called carbon fixation.

The term dark reaction is misleading because the process can take place in both light and darkness.

The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light.

This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.

Hope this helps ✌✌
