Prepare for NEET Biology Respiration in Plants (R.Q) with MCQs & PYQs on NEET.GUIDE. Access free practice, previous year questions, and expert help to understand Respiratory Quotient and substrate utilization ratios.
The respiratory quotient (RQ) is defined as the:
Ratio of the volume of O2 consumed to the volume of CO2 evolved
Ratio of the volume of CO2 evolved to the volume of O2 consumed
Volume of O2 consumed per unit time
Volume of CO2 evolved per unit time
Which of the following has an RQ value less than 1?
Carbohydrates
Proteins
Fats
Organic Acids
If the RQ value is 0.9, the respiratory substrate is likely to be:
Carbohydrate
Protein
Fat
Organic Acid
A plant is respiring with an RQ of greater than 1. What substrate is it likely using?
Carbohydrate
Fat
Protein
Organic acid
The respiratory quotient of which of the following substrate is less than one ?
Proteins
Organic acids
Carbohydrates
Malic acid
Respiratory Quotient (RQ) is one in case of
Fatty acids
Nucleic acids
Carbohydrates
Organic acids
The respiratory quotient during cellular respiration would depend on the
Nature of enzymes involved
Nature of the substrate
Amount of carbon dioxide released
Amount of oxygen utilized
