- carbohydrates are used as respiratory substrate
- volume of carbon dioxide evolved is less than volume of oxygen consumed
- volume of carbon dioxide evolved is more than volume of oxygen consumed
- volume of carbon dioxide evolved is equal, to volume of oxygen consumed
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
When respiratory quotient (RQ) is less then one in a respiratory metabolism, it means that respiratory substrate is either fat or protein. Both of the respiratory substrate always possess respiratory quotient less than one $(0.5-0.9)$. If Ris one, then carbohydrates are used as respiratory substrate. When the volume of $ CO_{2} $ evolved is more than the volume of oxygen consumed, then the respiratory substrates are organic acids, whose respiratory quotient is always more than one $(1.3-4.0)$.

Respiration in Plants
Respiration in plants is a process that entails the production of energy in plants. This process can simply be described as the intake of Oxygen and the release of Carbon Dioxide as an outcome of the oxidation of complex organic compounds. Though plants do not have any specific organ to balance the process of respiration, their stems, roots, and leaves do this work at a very low rate than other living beings. The process of respiration is very crucial for the plants to sustain the growth of the plant tissues.
This process can be stated as-
\[C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + \text{Energy}\]
