Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar, glyceraldehyde-3-phosphate (G3P). This stage gets its name because NADPH donates electrons to, or reduces, a three-carbon intermediate to make G3P.

three

To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle.

three carbons atoms

7. Why is it necessary to have six CO, entering the chloroplast? The photosynthesis reaction must be balanced. Six carbons are needed to make glucose, so six CO, molecules are needed.

three molecules

Ribulose-1,5-bisphosphate carboxylase-oxygenase, commonly known by the abbreviations RuBisCo, rubisco, RuBPCase, or RuBPco, is an enzyme involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthetic organisms to energy-rich molecules …

Chloroplasts are filled with RuBisCO, which comprises half of the protein. This makes RuBisCO the most plentiful single enzyme on the Earth.

Lignin. Lignin is a complex polyphenolic macromolecule composed mainly of beta-O4-aryl linkages. After cellulose, lignin is the second most abundant biopolymer and is one of the primary structural components of most plants.

Carbohydrates (example cellulose, starch, glycogen, glucose, fructose etc) are the most abundant biomolecules on earth. The carbohydrates are produced by the reduction of atmospheric carbon dioxide with the help of light energy in the process of photosynthesis.

Cellulose

The most abundant biomolecule in nature is carbohydrate, but my biology textbook states “Protein is the most abundant organic compound in protoplasm”.

But in ncert book its given that glucose is more abundant. The most abundant organic compound on Earth is cellulose, which is made up of various glucose molecules all connected together. Cellulose is originated in the cell walls of every plant, which is most abundant organic molecule.

Glossary

No matter what the year, sulfuric acid heads the list as the number-one produced chemical worldwide. The major use of sulfuric acid is in the production of fertilizers — ammonium sulfate and superphosphate. However, sulfuric acid is also used in other products, including the following: Detergents.
