Overview of Photosystem II and Photosystem I
In the light-dependent reactions of photosynthesis, chlorophyll molecules in Photosystem II (PSII) absorb light energy, which excites electrons. These high-energy electrons are transferred through a series of proteins and ultimately reach Photosystem I (PSI).
Electron Transport Chain
- Excited electrons from PSII move through the electron transport chain (ETC).
- As electrons travel, they release energy used to pump protons into the thylakoid lumen, creating a proton gradient.
Role of NADP+ and NADPH
- At the end of the ETC, electrons are transferred to NADP+, a coenzyme that acts as an electron carrier.
- The reduction of NADP+ occurs when it picks up electrons and protons (H+) to form NADPH.
Importance of NADPH
- NADPH is crucial for the Calvin cycle, which synthesizes glucose from carbon dioxide.
- It serves as a reducing agent, donating electrons to assist in the conversion of carbon compounds.
Conclusion
Therefore, the correct answer is d) NADP to NADPH. This process highlights the integral role of NADP+ in capturing electrons, ultimately facilitating the transformation of light energy into chemical energy stored in glucose.
