MCQ
The conversion of PGA into glyceraldehyde 3-phosphate occurs during
  • A
    regeneration
  • B
    photorespiration
  • C
    carboxylation
  • D
    reduction
✓

Answer

D. reduction
Explanation:
During reduction stage of Calvin cycle, a glucose molecule is formed through a series of reactions. Each molecule of 3PGA is phosphorylated using ATP and 1, 3-bisphosphoglyceric acid is formed. Each molecule of 1,3-bisphosphoglyceric acid is converted into glyceraldehyde 3-phosphate (G3P) using NADPH. Glyceraldehyde 3-phosphate is converted into one molecule of glucose through a series of reactions that are reversal of glycolysis. So, this is also called glycolytic reversal.
