According to the description of the Calvin cycle, how many molecules of G3P exit the cycle for every three molecules of CO2 fixed, and what is its primary fate?

  • A: Two G3P molecules exit and are converted to glucose.
  • B: One G3P molecule exits and is converted to glucose and other organic molecules.
  • C: Three G3P molecules exit and are used to regenerate RuBP.
  • D: Six G3P molecules are produced, with all of them converted to glucose.

Explanation

Concept 10.4 clearly states that 'One molecule of G3P exits the cycle per three CO2 molecules fixed and is converted to glucose and other organic molecules.' This highlights the net output of the Calvin cycle.
