glucose has ____ carbon atoms, which means it takes ____ turns of the calvin cycle to create one glucose molecule.
○ six, three
○ six, six
○ three, two
○ three, three

Explanation:

The chemical formula of glucose is \( C_6H_{12}O_6 \), so it has 6 carbon atoms. In the Calvin cycle, each turn fixes 1 carbon (in the form of \( CO_2 \)). To make a glucose molecule with 6 carbon atoms, 6/2 = 3 turns (since each turn actually produces a 3 - carbon compound, and two 3 - carbon compounds combine to form glucose).

Answer:

A. Six, three
