NEETBotanyPhotosynthesis in Higher Plants
Photosynthetic Components Function A. Excited Electrons in PS II 1. Reduce NADP+ to NADPH + H+. B. NADP+ 2. Passes electrons through a series of cytochromes. C. Excited Electrons in PS I 3. Absorbs light at 680 nm to excite electrons. D. Electron Transport Chain 4. Moves electrons downhill from PS II to PS I.
Options
- AA - 3, B - 1, C - 4, D - 2
- BA - 4, B - 3, C - 1, D - 2
- CA - 1, B - 4, C - 2, D - 3
- DA - 2, B - 3, C - 4, D - 1
Correct answer
A. A - 3, B - 1, C - 4, D - 2
Step-by-step solution
A - 3: Excited electrons in PS II are absorbed at 680 nm and excited to a higher energy state. B - 1: NADP+ is reduced to NADPH + H+ when it accepts electrons. C - 4: Excited electrons in PS I are moved downhill to reduce NADP+. D - 2: The electron transport chain passes electrons through cytochromes from PS II to PS I.
