During the light dependent reaction
During the light dependent reaction
- A) glucose is formed
- B) carbon IV oxide is fixed
- C) NADPH and ATP are synthesized using electron released from water
- D) water is split and the electrons produced are used for glucose synthesis
Correct Answer: C) NADPH and ATP are synthesized using electron released from water
Explanation
During photosynthesis, plants undergo two main processes: light-dependent reactions and light-independent reactions. The light-dependent reactions occur in the thylakoid membranes and require light energy to produce ATP and NADPH, which are used in the light-independent reactions. The given question focuses on the light-dependent reactions and asks what happens during this process. Option A, glucose formation, occurs during the light-independent reactions. Option B, carbon IV oxide fixation, occurs during the Calvin cycle, which is also part of the light-independent reactions. Option D, splitting of water and using the electrons for glucose synthesis, is not a correct statement. Therefore, option C is the correct answer. During the light-dependent reactions, photosystem II absorbs light energy and uses it to split water molecules into oxygen, hydrogen ions, and electrons. The electrons are then passed through a series of electron carriers, which ultimately results in the synthesis of ATP and NADPH. These energy-rich molecules are then used in the light-independent reactions to produce glucose.
