4. Q2. True or false: Each turn of the Calvin cycle produces one molecule of glucose? If false, how would it be true?

The statement is false
Each G3P molecule is made up of three carbon atoms, and each calvin cycle forms a single extra carbon atom for G3P, which means three calvin cycles are required to make one molecule of G3P. Glucose is six carbon atom while G3P has 3 carbon atoms, thus, we need 6 calvin cycles to form a 6-carbon atom molecule. Each turn of calvin cycle results in the fixation of one molecule of CO2.
