In the majority of the plants, the first stable intermediate of carbon dioxide reduction is a three-carbon compound. Hence, this type of carbon reduction is called as C3 cycle. In C3 cycle, the initial carboxylation is brought about by RuBisCo, which carboxylates Ribulose 1,5 bisphosphate (RUBP) into phosphoglyceric acid. The phosphoglyceric acid is later on reduced to phosphoglyceraldehyde, which is used to synthesize sugars and recycle RUBP. Simple sugars like glucose and fructose are first produced. They are converted to sucrose for transportation and later on into starch for long term storage.

Photosynthesis in Green Plants

Photosynthesis is the process by which green plants manufacture their food using sunlight, carbon dioxide, and water. The process takes place in the chloroplasts present in the leaves of the plant. During photosynthesis, the plant produces glucose, which is a type of simple sugar.

The First Substance Produced in Photosynthesis

The first substance produced in photosynthesis is glucose. It is the primary product of photosynthesis and is produced in the chloroplasts of the plant. Glucose is a simple sugar that is used by the plant as a source of energy. It is also used to manufacture other substances required by the plant, such as starch, fats, and proteins.

Other Substances Produced in Photosynthesis

Starch: Starch is a complex carbohydrate that is made up of many glucose molecules. Plants store glucose in the form of starch, which is used when the plant needs energy.

Fats: Fats are complex molecules that are made up of glycerol and fatty acids. Plants produce fats from glucose and use them as a source of energy.

Proteins: Proteins are complex molecules that are made up of amino acids. Plants produce proteins from glucose and use them for growth and repair.

Conclusion

In conclusion, the first substance that a green plant makes in photosynthesis is glucose. Glucose is a simple sugar that is used by the plant as a source of energy and to manufacture other substances required by the plant, such as starch, fats, and proteins.

Read the following passage to answer the following questions:Proteins are polypeptide chains made up of amino acids. There are 20 types of amino acids joined together by peptide bond between amino and carboxylic group. There are two kinds of amino acids, Essential amino acids and Non-essential amino acids. The Primary structure of protein is the linear sequence of amino acids in a polypeptide chain. The first amino acid of sequence is called N-terminal amino acids and last amino acid of peptide chain is called C-terminal amino acids. The secondary structure proteins forms helix. There are three types of secondary structure: a helix, P pleated and collagen helix. In tertiary structure long protein chain is folded upon itself like a hollow woollen ball to give three-dimensional view of protein. In quaternary structure, each polypeptide develops its own tertiary structure and function as subunit of protein.Q. The tertiary structure of a protein contains
