R.Q= CO2/O2 = 4/1 = 4.
For example, oxidation of tripalmitin, a common fat, gives an RQ of 0.7: (6.10)C51H98O6 + 72.5O2 → 51CO2 + 49H2O (51CO2/72.5O2) = 0.7. In plants such as the succulents that oxidize organic acids, the RQ may be considerably more than 1.
So the correct option is 'malic acid'.
The respiratory quotient of malic acid is 1.33. Respiratory quotients is the ratio of the amount of carbon dioxide released to the amount of oxygen consumed in the complete oxidation of a substrate.
So, at night when oxygen is absorbed, the carbohydrates are partially oxidized to organic acids without the formation of CO2. So, the value of R.Q. remains zero.
value of organic acids is greater than one because they already have a good amount of oxygen in their molecule that can be oxidised which decreases the requirement of external O2. So, correct the answer is 'Organic acid'.
RQ values for fat, protein, and carbohydrate are 0.7, 0.8, and 1.0, respectively.
The RQ of anaerobic respiration is infinite. This is because, in anaerobic respiration, the total volume of oxygen consumed is zero as this process occurs in the absence of oxygen and only carbon dioxide is produced. Therefore : RQ = CO2 / O2 = 2/0 = infinity.
So the correct option is 'Tripalmitin'.
The respiratory quotient of the reaction given below is 2(C51H98O6) + 145 O2→ 102CO2 + 90H2O + energy.
So the correct option is '0.7'.
Solution : R.Q. is the ratio of volume of `CO_(2)` released to the volume of `O_(2)` taken up in respiration. Value of R.Q. : Oxalic acid = 4, Tripalmithin = 0.7, Glucose = 1.

Glycolysis: Sugars, glycerol from fats, and some types of amino acids can enter cellular respiration during glycolysis. Pyruvate oxidation: Some types of amino acids can enter as pyruvate.
Correct answer is (a) Zero.
Lactic acid fermentation
Respiratory quotient (R.Q): The ratio of volume of carbon dioxide liberated and the volume of oxygen consumed during respiration is known as respiratory quotient.
RQ is the ratio of the volume of carbon dioxide produced divided by the volume of oxygen consumed during the same time period (VCO2/VO2). Measurements of whole body RQ reflect substrate utilization at the time of measurement. The physiologic RQ ranges between 0.70 and 1.00 and varies with substrate oxidation.
Solution : The ratio of the volume of `CO_(2)` produced to the volume of `O_(2)` used in a unit time is called respiratory quotient (RQ) . RQ for carbohydrates , fats and proteins is 1, 07 and 0,85 respectively .
No significant differences were found in baseline (pre-drink) REE or RQ values across days: the mean baseline REE values for glucose, galactose and fructose were 4·27 (se 0·30), 4·45 (se 0·33) and 4·43 (se 0·34) kJ/min, respectively; the mean baseline RQ values for glucose, galactose and fructose were 0·81 (se 0·02), 0 ...
The respiratory quotient is less than one in fats.
If the respiratory substrate is fat, then Respiratory quotient of the respiring cells will be less than 1, because the volume of CO2 evolved is quite less in comparison to the volume of O2 being consumed.
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis.
Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.
Respiratory quotient (RQ) is the ratio of the carbon dioxide evolved into the oxygen consumed and is a measure of the basal metabolic rate. The RQ value of carbohydrates is 1.0. RQ of fats is 0.7. RQ of proteins is 0.8.
The no. of carbon dioxide molecules released is 102. The RQ value is RQ = 102/145. Therefore the RQ is 0.7.
