Options

A. 60
B. 15
C. 30
D. 90

Answer

To determine how many Calvin cycles are required to produce 5 molecules of glucose, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Calvin Cycle**: The Calvin cycle is a part of photosynthesis where carbon dioxide is converted into glucose. Each complete cycle produces a fraction of glucose.

2. **Determine Glucose Production per Cycle**: It is known that one complete turn of the Calvin cycle produces 1/6 of a glucose molecule.

3. **Calculate Cycles for One Glucose Molecule**: To produce 1 molecule of glucose, we need to run the Calvin cycle 6 times because:
\[ 1 \text{ glucose} = 6 \times \left(\frac{1}{6} \text{ glucose per cycle}\right) \]

4. **Calculate Cycles for Five Glucose Molecules**: To find out how many cycles are needed for 5 glucose molecules, we multiply the number of cycles needed for one glucose by 5:
\[ 5 \text{ glucose} = 5 \times 6 = 30 \text{ cycles} \]

5. **Conclusion**: Therefore, to produce 5 molecules of glucose, we need to run the Calvin cycle 30 times.

### Final Answer:
30 Calvin cycles are required to produce 5 molecules of glucose.
