Q. During anaerobic respiration in yeast
A) $H_{2}O$ and $CO_{2}$ are end-products
B) $CO_{2}$ , ethanol and energy are end-products
C) $CO_{2}$ , and H₂O are end-products
D) $CO_{2}$ , acetic acid and energy are end-products
Explanation
When oxygen is not available, yeast or some other microbes respire anaerobically. In case of anaerobic respiration, the value of respiratory quotient is not utilized, eg, $C_{6}H_{12}O_{6}$ $\overset{Zymase\ }{\rightarrow}$ 3$C_{2}H_{5}$OH + 2C$O_{2}$ + Energy Glucose Ethyl alcohol
