The time taken from the fixation of `CO_(2)` to the formation of one glucose molecules is about…………………. Seconds

Options

A. 20
B. 40
C. 60
D. 90

Answer

To determine the time taken from the fixation of CO₂ to the formation of one glucose molecule, we can follow these steps:

1. **Understand the process of photosynthesis**: Photosynthesis occurs in two main stages - the light-dependent reactions and the light-independent reactions (Calvin cycle). The fixation of CO₂ occurs during the Calvin cycle.

2. **Identify the time frame for glucose formation**: According to the information provided, the time taken for the fixation of CO₂ to the formation of one glucose molecule is approximately 90 seconds.

3. **Choose the correct answer**: Based on the information given, the correct answer to the question is 90 seconds.

Final Answer: The time taken from the fixation of CO₂ to the formation of one glucose molecule is about **90 seconds**.
