Photosystem I have a form of chlorophyll a, which absorbs best the light of
Correct answer: A. 700 nm
- A. 700 nm
- B. 730 nm
- C. 680 nm
- D. 660 nm
Explanation
Photosystem I contains a specific form of chlorophyll a known as P700, which is named after its optimal absorption of light at 700 nm. This is the characteristic peak of absorption that distinguishes it from Photosystem II, which absorbs best at 680 nm. The other options (730 nm, 680 nm, and 660 nm) are incorrect because they do not correspond to the primary absorption wavelength of Photosystem I.
