Photosynthesis and PGA as the first CO2 fixation product

Photosynthesis is a process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. The process of photosynthesis can be divided into two phases: the light-dependent reactions and the light-independent reactions.

During the light-independent reactions, carbon dioxide fixation occurs where carbon dioxide is converted into an organic compound. The first stable product of carbon dioxide fixation is PGA (phosphoglyceric acid).

The discovery of PGA as the first CO2 fixation product in photosynthesis was made by scientists Melvin Calvin, Andrew Benson, and James Bassham in the 1950s.

PGA and algae

The discovery of PGA as the first CO2 fixation product in photosynthesis was made using algae. Algae are simple, plant-like organisms that can perform photosynthesis. They are classified into different groups based on their pigmentation and cell wall composition.

Algae are important organisms in the study of photosynthesis as they are capable of performing both oxygenic and anoxygenic photosynthesis. Additionally, algae are found in a variety of habitats, ranging from freshwater ponds to marine environments.

The discovery of PGA in algae was a significant breakthrough as it helped scientists understand how carbon dioxide fixation occurs in photosynthesis. It also paved the way for further research into the process of photosynthesis and its role in sustaining life on Earth.

Conclusion

In conclusion, PGA was discovered as the first carbon dioxide fixation product in photosynthesis using algae. This discovery was made by scientists Melvin Calvin, Andrew Benson, and James Bassham in the 1950s. The discovery of PGA in algae was a significant breakthrough in the study of photosynthesis, as it helped scientists understand the process of carbon dioxide fixation and its role in sustaining life on Earth.

PGA as the first CO2 fixation product will discovered in algae. Melvin Calvin used radioactive 14c algal photosynthetic studies.chlorella was used in the study .This led to the discovery that the first co2 fixation product was the three carbon organic acid i.e.3-phosphoglyceric acid(PGA)
