If the volume of CO2 liberated during respiration is more than the volume of O2 used, the respiratory substrate will bea)Fatb)Organic acidc)Proteind)CarbohydrateCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

This is because a respiratory quotient (RQ) for Organic acids is more than one. fats and proteins have RQ less than 1. While carbohydrate have RQ=1

RQ = (volume of CO2 evolved)÷(volume of O2 required)

RQ = (volume of CO₂ evolved)÷(volume of O₂ required)

Answer

Explanation:

Organic acid:
When the volume of CO2 liberated during respiration is more than the volume of O2 used, it indicates anaerobic respiration. In anaerobic respiration, organic acids like lactic acid or ethanol are produced as byproducts. This occurs when there is a lack of oxygen supply to the cells, forcing them to switch to anaerobic respiration for energy production.

Respiratory Substrate:
The respiratory substrate in this scenario would be an organic acid. Organic acids are used as substrates in anaerobic respiration to produce energy in the absence of oxygen. These substrates are broken down through fermentation processes to generate ATP, the energy currency of cells.

Comparison with other options:
- Fat: Fat is a storage form of energy and is primarily used in aerobic respiration, where oxygen is required for the breakdown of fatty acids. In anaerobic conditions, fats are not the preferred substrates for energy production.
- Protein: Proteins are not the main respiratory substrates in cellular respiration. They are usually used for other cellular functions and are not the preferred source of energy during respiration.
- Carbohydrate: Carbohydrates are the primary substrates for respiration in both aerobic and anaerobic conditions. However, in the case where CO2 production exceeds O2 consumption, organic acids are more likely to be the respiratory substrates.

Therefore, in a situation where the volume of CO2 liberated during respiration is more than the volume of O2 used, the respiratory substrate would be an organic acid.
