How many molecules of `CO_2` will be required to produce 6 molecules of glucose ?

Options

A. 38
B. 36
C. 40
D. 32

Answer

To determine how many molecules of \( CO_2 \) are required to produce 6 molecules of glucose, we can follow these steps:

### Step 1: Understand the process of glucose production
Glucose is produced through photosynthesis, specifically during the Calvin cycle. In this cycle, \( CO_2 \) is fixed to produce glucose.

### Step 2: Know the relationship between \( CO_2 \) and glucose
From the Calvin cycle, we know that it takes 6 molecules of \( CO_2 \) to produce 1 molecule of glucose. This is a key relationship that we will use to solve the problem.

### Step 3: Calculate the \( CO_2 \) needed for 6 molecules of glucose
Since 6 molecules of \( CO_2 \) are required for 1 molecule of glucose, we can set up a proportion to find out how many \( CO_2 \) molecules are needed for 6 molecules of glucose:
\[ \text{For 1 glucose: } 6 \, CO_2 \\ \text{For 6 glucose: } 6 \times 6 \, CO_2 = 36 \, CO_2 \]

### Step 4: Conclusion
Thus, to produce 6 molecules of glucose, **36 molecules of \( CO_2 \)** are required.

### Final Answer
The answer is **B - 36**.
