Respiration In Plants

Sugar is broken down partially into alcohol and CO2 is evolved.

The above reaction is of alcoholic fermentation. During this process there is a conversion of sugars into alcohol and carbon dioxide, in the absence of oxygen. The substrate for this process of glucose and it starts with the process of gl;ycolysis that produces pyruvates. In the absence of oxygen this pyruvate gets converted into ethanol and energy along with CO2 as a by-product.

The correct answer is:

Option 3: 1.0

Explanation:

The Respiratory Quotient (RQ) is the ratio of the volume of carbon dioxide (CO₂) produced to the volume of oxygen (O₂) consumed during respiration.

For glucose (C₆H₁₂O₆), the complete aerobic respiration process is:

For each molecule of glucose, 6 molecules of CO₂ are produced for every 6 molecules of O₂ consumed.

Thus, the RQ for glucose is:

Therefore, the RQ of glucose is 1.0.
