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.

What other recent hypotheses would corroborate the hypothesis that life on earth originated in space? (choose all that apply.)?

LuckyWell [14K]

The answer would be meteorites containing amino acids. Most of the amino the amino acids revealed in the new investigation were not guaranteed up in proteins or polymers. Furthermore, the most plentiful amino acids originate in biology are those that are set up in proteins, but such "proteinogenic" amino acids signify only a small fraction of the amino acids originate in the meteorites.
