In Calvin cycle 1,3-biophosphoglyceric acid is reductive by dephosphorylated to form

Options

A. 3-PGA
B. G-3-P
C. PEP
D. RuBP

Answer

**Step-by-Step Solution:**

1. **Understanding the Calvin Cycle**: The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms. It is responsible for converting carbon dioxide and other compounds into glucose.

2. **Identifying the Compound**: The question asks about the reduction of 1,3-bisphosphoglyceric acid (1,3-BPG) during the Calvin cycle. This compound is an intermediate in the cycle.

3. **Reduction and Dephosphorylation**: In the Calvin cycle, 1,3-bisphosphoglyceric acid undergoes a reduction process. This involves the addition of electrons (reduction) and the removal of a phosphate group (dephosphorylation).

4. **Formation of Glyceraldehyde 3-Phosphate**: The reduction of 1,3-bisphosphoglyceric acid leads to the formation of glyceraldehyde 3-phosphate (G3P), also known as 3-phosphoglyceraldehyde (3-PGAL). This is a crucial product of the Calvin cycle.

5. **Conclusion**: Therefore, the final answer to the question is that 1,3-bisphosphoglyceric acid is reduced and dephosphorylated to form glyceraldehyde 3-phosphate (G3P).
