Question

What is the fate of G3P produced in the Calvin cycle?
Options
A Oxidized in mitochondria
B Used to form glucose and regenerate RuBP
Correct Answer
C Converted into oxygen
D Stored as ATP
Correct Answer

Option B is the correct answer.

Detailed Explanation

Glyceraldehyde-3-phosphate (G3P) is a three-carbon sugar. Some G3P molecules exit the cycle to form glucose and other organic molecules, while most are used to regenerate the CO2 acceptor, RuBP.

Hint

Think of G3P as the useful product that gets converted to sugar and also recycles the starting material.
