To generate 1 molecule of glucose, how many turns of Calvin cycle are needed?

Explanation

To determine how many turns of the Calvin cycle are needed to generate one molecule of glucose, we can follow these steps:

### Step 1: Understand the Calvin Cycle
The Calvin cycle, also known as the dark reaction, is a crucial part of photosynthesis that occurs in the stroma of chloroplasts. It consists of three main stages: carboxylation, reduction, and regeneration.

### Step 2: Identify the Carbon Fixation
In the Calvin cycle, carbon dioxide (CO2) is fixed into an organic molecule. The first step involves the enzyme RuBisCO catalyzing the reaction between CO2 and ribulose bisphosphate (RuBP), which produces a 3-carbon compound.
