During the Calvin cycle, the reduction of 3-phosphoglyceric acid (PGA) leads to the formation of:
Show answer and explanation
Correct answer: Triose phosphate
The reduction step involves the use of ATP and NADPH to convert 3-PGA into triose phosphates (G3P). These triose phosphates are the precursors for the synthesis of sucrose and starch.
