Nadya [2.5K]

The correct answer is - the release of methane from thawed permafrost.

In the past decade it has been noticed that the levels of methane are increasing in the atmosphere, and the biggest ''producer'' of this methane is the melting permafrost. There's huge amounts of methane trapped underground bellow the permafrost. But the permafrost is melting because of the global worming, so the methane is free to come out and go up in the atmosphere.

4. Which pathway represents the flow of electrons during photosynthesis? (1 point) A.) H2O > Photosystem I > Photosystem I

Yuki888 [10]

Answer:

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

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.
