Question

the figure above shows the calvin cycle. how many turns of this cycle are required to make glucose (c6h12o6)?

Explanation:

Step1: Recall carbon - atom content

Glucose ($C_6H_{12}O_6$) has 6 carbon atoms. Each turn of the Calvin cycle fixes 1 molecule of $CO_2$, which contains 1 carbon atom.

Step2: Calculate number of turns

To make a glucose molecule with 6 carbon atoms, the number of turns of the Calvin cycle required is equal to the number of carbon atoms in glucose. So, the number of turns = 6.

Answer:

6
