Question

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

Explanation:

Step1: Understand glucose composition

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

Step2: Calculate number of turns

To make a glucose molecule with 6 carbon atoms, we need 6 turns of the Calvin - cycle since 1 carbon is fixed per turn.

Answer:

6
