In photosynthesis energy from light reaction to dark reaction Is transferred in the form of:
Correct answer: C. NADPH
- A. ADP
- B. AMP
- C. NADPH
- D. Chlorophyll
Explanation
ADP (adenosine diphosphate) is a molecule that is used to store energy in cells. It is the breakdown product of ATP, which is the main energy currency of cells. However, ADP does not contain any electrons, so it cannot carry energy from the light reactions to the dark reactions. AMP (adenosine monophosphate) is a simpler molecule than ATP. It is not as efficient at storing energy as ATP, and it is not used as an energy currency in cells. It also does not contain any electrons, so it cannot carry energy from the light reactions to the dark reactions. NADPH (nicotinamide adenine dinucleotide phosphate) is a molecule that is used to carry electrons in cells. It is produced in the light reactions of photosynthesis, and it is used in the dark reactions to reduce carbon dioxide. NADPH contains two high-energy electrons, which are used to drive the dark reactions. Chlorophyll is a molecule that absorbs light energy and uses it to drive the light reactions of photosynthesis. It is not involved in the transfer of energy from the light reactions to the dark reactions. Therefore, the answer is C) NADPH NADPH is the molecule that carries energy from the light reactions to the dark reactions in photosynthesis.
