Question
Biology Question on Calvin cycle
In an experiment demonstrating the evolution of oxygen in Hydrilla, Sodium bicarbonate is added to water in the experimental set-up. What would happen if all other conditions are favourable ?
A
Amount of oxygen evolved increases as the availability of carbon dioxide increases.
B
Amount of oxygen evolved decreases as the availability of carbon dioxide increases.
C
Amount of oxygen evolved increases as carbon dioxide in water is absorbed by sodium bicarbonate.
D
Amount of oxygen evolved decreases as carbon dioxide in water is absorbed by sodium bicarbonate.
Answer
Amount of oxygen evolved increases as the availability of carbon dioxide increases.
Explanation
Solution
Addition of NaHCO3 causes the availability of CO2 for photosynthesis and result more O2 evolution
