All of the aboveWhich of the following statements about the dark reactions is true? a. Dark reactions occur in the thylakoids of chloroplasts. b. Light energy is converted to chemical energy during the dark reactions. c. Carbon dioxide is converted to sugar using ATP and NADPH during the dark reactions. d. All of the above

Answer 1

The correct answer is C !! Carbon dioxide is converted to sugar using ATP and NADPH (formed in light reaction) during dark reaction !! It is also called Calvin Cycle !!

Go with C !!

Answer 2

Answer: The correct answer is -

Option C).

Explanation:

Dark reaction (also termed as calvin cycle) is the second stage of the photosynthesis (process of formation of food in green plants and algae) that occurs in the stroma of chloroplast.

This stage is dependent on the products of light reaction (first stage of photosynthesis) that are NADPH and ATP.

Using these products, CO2 (carbon dioxide) is fixed and converted into food (glucose, which is a carbohydrate or sugar).

Thus, option C) is the right answer.
