During Calvin cycle the total number of `CO_(2)` ATP and NADPH molecules utilised and glucose, ADP and NADP molecules generated is

Options

A. 31
B. 36
C. 61
D. 67

Answer

To solve the question regarding the Calvin cycle, let's break down the information step by step.

### Step 1: Identify the molecules utilized in the Calvin cycle
In the Calvin cycle, the following molecules are used:
- **Carbon Dioxide (CO₂)**: 6 molecules
- **ATP**: 18 molecules
- **NADPH**: 12 molecules

### Step 2: Identify the molecules generated in the Calvin cycle
The products generated from the Calvin cycle include:
- **Glucose**: 1 molecule
- **ADP**: 18 molecules
- **NADP⁺**: 12 molecules

### Step 3: Calculate the total number of molecules utilized and generated
Now, we will sum up all the molecules utilized and generated:
- Total utilized:
- CO₂: 6
- ATP: 18
- NADPH: 12
- Total utilized = 6 + 18 + 12 = 36

- Total generated:
- Glucose: 1
- ADP: 18
- NADP⁺: 12
- Total generated = 1 + 18 + 12 = 31

### Step 4: Combine the totals
Now, we add the total utilized and total generated:
- Total = Total utilized + Total generated
- Total = 36 + 31 = 67

### Final Answer
Thus, during the Calvin cycle, the total number of CO₂, ATP, and NADPH molecules utilized and glucose, ADP, and NADP molecules generated is **67**.
