Question

The trapping center of light energy in photosystem- I is

• A. P- 660
• B. P- 680
• C. P- 700
• D. P- 720

Answer 1

The correct option is C P- 700

P- 700 is the reaction centre for photosystem I. Its absorption spectrum peaks at 700 nm. When photosystem I absorbs light, an electron is excited to a higher energy level in the P ${}_7$${}_0$${}_0$ chlorophyll.
