Answer 1

4. Which pathway represents the flow of electrons during photosynthesis?

I think the correct answer from the choices listed is option D, H20 > NADP > Calvin cycle.

5. Which process does NOT release energy from glucose?

I think the correct answer is option B. The process which does not release energy from glucose is photosynthesis.

Answer 2

Answer:

4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D. $H_{2}O$ > NADP > Calvin cycle.

• Electron is first provided to the photo-system II by the phtolysis of water.
• Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome $b_{6}f$.
• Finally, electron from the photo-system II is used to reduce NADP to NADPH.
• NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.

5. The correct answer is B.) photosynthesis.

• Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
• In light independent phase of photosynthesis, it requires ATP and NADPH  in order to synthesize food.
• Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.
