A) \[{{H}_{2}}O\] and \[C{{O}_{2}}\] are end products
B) \[C{{O}_{2}}\], ethanol and energy are end products
C) \[C{{O}_{2}}\] and \[{{H}_{2}}O\] are end products
D) \[C{{O}_{2}}\], acetic acid and energy are end products
Correct Answer: B
Solution :
When oxygen is not available, yeast or some other microbes respire anaerobically. In case of anaerobic respiration the value of respiratory quotient is much more than unity as oxygen is not utilized, e.g., \[_{\text{Glucose}}^{{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{12}}}{{\text{O}}_{\text{6}}}}\xrightarrow[\text{ethylalcohol}]{\text{zymase}}\underset{\text{ethylalcohol}}{\mathop{\text{3}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}}}\,\text{+2C}{{\text{O}}_{\text{2}}}\text{+energy}\]\[\text{RQ=}\frac{\text{2C}{{\text{O}}_{\text{2}}}}{{{\text{O}}_{\text{2}}}}\text{=}\,\text{2}\,\text{or}\,\text{ }\!\!\alpha\!\!\text{ }\]You need to login to perform this action.
