NEETBotanyPhotosynthesis in Higher Plants
How are the pigments organized in the light reactions?
Options
- AAs a single large complex
- BInto two discrete photochemical light harvesting complexes
- CRandomly within the chloroplast
- DAs individual molecules
Correct answer
B. Into two discrete photochemical light harvesting complexes
Step-by-step solution
Light reactions or the ‘Photochemical’ phase include light absorption, water splitting, oxygen release, and the formation of high-energy chemical intermediates, ATP and NADPH. Several protein complexes are involved in the process. The pigments are organised into two discrete photochemical light harvesting complexes (LHC) within the Photosystem I (PS I) and Photosystem II (PS II). Within the Photosystem I (PS I) and Photosystem II (PS II). These are named in the sequence of their discovery, and not in the sequence i
