Isotopes employed to study the process of photosynthesis reaction.a)S35 and P32b)C14 and O18c)N14 and Co60d)N14 and O18Correct answer is option 'B'. Can you explain this answer?

Question

Answer

Correct reason is C14 and O18 was radioactive so it helped in study of photosynthesis.

Answer

Photosynthesis is a redox reaction in which carbon dioxide is reduced to sugars in dark reaction and water is oxidised to release oxygen in light reaction of photosynthesis.

C14 label was used to trace the path of carbon in the dark reaction in C3 plants by Calvin, Benson, & Basham.

The O18 lable was used by Rumen & Kamen to experimentally prove that the source of oxygen released during light reaction of photosynthesis is water...

So, correct answer is option (B)...

$$Hope it's help... $$

Answer

And is B

Answer

Isotopes employed to study the process of photosynthesis reaction:

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. Isotopes, which are atoms with the same number of protons but different number of neutrons, can be used to study this process.

C14 and O18:

Isotopes of carbon and oxygen, namely C14 and O18, are commonly employed to study the process of photosynthesis. Here's why:

Carbon-14 (C14):
- Carbon is an essential element in the process of photosynthesis as it forms the backbone of organic compounds.
- C14 is a radioactive isotope of carbon that decays over time, and its presence can be detected using specialized techniques.
- By introducing C14 into the carbon dioxide that is supplied to the plants during photosynthesis, scientists can track the movement and transformation of carbon within the plant.
- This allows researchers to study the rates of carbon fixation, the pathways through which carbon is assimilated into different organic compounds, and the overall efficiency of photosynthesis.

Oxygen-18 (O18):
- Oxygen is another key element in photosynthesis, as it is involved in the production of glucose and the release of oxygen.
- O18 is a stable isotope of oxygen that can be distinguished from the more common O16 isotope.
- By labeling the water molecules used by plants during photosynthesis with O18, scientists can trace the movement of oxygen atoms within the plant.
- This enables the measurement of oxygen production rates, as well as the identification of specific oxygen-containing compounds produced during photosynthesis.

Conclusion:

In conclusion, C14 and O18 isotopes are employed to study the process of photosynthesis. C14 helps track the movement of carbon, while O18 allows the tracing of oxygen atoms. These isotopes provide valuable insights into the dynamics and efficiency of photosynthesis, aiding in our understanding of this crucial biological process.
