Single correct option

The light-dependent reactions of photosynthesis take place in the
  1. A. stroma of the chloroplast
  2. B. mitochondrial matrix
  3. C. cytoplasm
  4. D. thylakoid membranes of the chloroplast
Show answer and solution

Answer: (D) thylakoid membranes of the chloroplast

Chlorophyll is located in the thylakoid membranes (grana), where light splits water and forms ATP and NADPH. The Calvin cycle (the dark reaction) occurs in the stroma and uses ATP and NADPH to fix CO2 into sugar. Mitochondria perform respiration, not photosynthesis.
