MCQ
Dark reaction:
  • A
    The carbon-fixing reaction which is a light-dependent process in which sugar molecules are formed from the carbon dioxide and water.
  • B
    This reactions require darkness for carbon dioxide fixation to produce glucose.
  • The carbon-fixing reaction which involves combination of hydrogen released by NADPH with $CO _2$ to form the final product glucose.
  • D
    In this, plants use $CO _2$ with ATP and NADPH from the light reactions to produce glucose takes place in the grana of the chloroplast.

Answer

Correct option: C.
The carbon-fixing reaction which involves combination of hydrogen released by NADPH with $CO _2$ to form the final product glucose.
(c) The carbon-fixing reaction which involves combination of hydrogen released by NADPH with $CO _2$ to form the final product glucose.
Explanation:
The dark reaction represents the second phase of photosynthesis, occuring in the stroma of chloroplasts. Also known as the biosynthetic phase or Calvin cycle. It uses ATP and NADPH for the fixation and reduction of $CO _2$ to form carbohydrate (glucose).
