Question
In succulent plants R.Q. is less than one because of
Open in App
Solution
The correct option is D Incomplete oxidation
In succulent plants, the stomata are open during night and during this time plants absorb carbon dioxide. During day time stomata are closed and no carbon dioxide is evolved. These plants respire during night time, when they can take oxygen through open stomata. The volume of carbon dioxide is less than typical aerobic respiration. In fact during night time, these plants fix carbon dioxide into organic acids. The respiratory substrates are incompletely oxidised and thus, respiratory quotient is less than one.
