Respiratory quotient of Tripalmitin is 0.73 and during respiration it releases 126 CO2 then how much O2 required for its respiration?? Answer: The actual ratio of the volume of carbon dioxide eliminated to the volume of oxygen consumed during the act of cellular respiration is called the respiratory quotient.
So, the correct answer is '0.7'
Value of R.Q. : Oxalic acid = 4, Tripalmithin = 0.7, Glucose = 1.
So the correct option is '0.7'.
The RQ is helpful in guiding the planning of nutritional therapy. The physiologic range for RQ values is 0.7 to 1.2 and is influenced by the relative contribution from fat, protein, and carbohydrate. RQ values for fat, protein, and carbohydrate are 0.7, 0.8, and 1.0, respectively.
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.
The no. of carbon dioxide molecules released is 102. The RQ value is RQ = 102/145. Therefore the RQ is 0.7.
So, the correct option is '1'
Various phospholipids such as phosphatidylcholine, diphosphatidylglycerol, phosphatidylethanolamine, and egg lecithin are used for making surrounding envelopes, while triglycerides such as tripalmitin, trilaurin, tricaprin, and trimyristin are used for constructing the internal lipid core (Amselem and Friedman, 1997).
The RQ of glucose is 1.0; of fat, 0.70; and of protein, 0.79–0.82. An RQ above 1.0 usually reflects a nonsteady state of hyperventilation, which is an inaccurate test situation.
Respiratory quotient or R.Q is defined as the ratio of carbon dioxide evolved to oxygen taken in for respiratory break down of a substrate. The value of R.Q for oxidation of carbohydrates is unity and less than one for oxidation of fats and proteins.
In rice and potato the main respiratory substrate is carbohydrates, for which, the RQ value is one.
Answer. RQ value of a potato is one.
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.
It can be illustrated through the example of tripalmitin fatty acid, which consumes 145 molecules of O2 for respiration while 102 molecules of CO2 are evolved. The RQ value for tripalmitin is 0.7.
It is denoted by RQ. Amount of oxygen consumed = 172.60. Was this answer helpful?
Solution : Respiratory Quotient (RQ) is the ratio of volume of `CO_(2)` exhaled and `O_(2)` inhaled during breathing . Value of RQ will be 1 when both the volumes are same and less than 1 when `CO_(2)` exhaled is less and `O_(2)` inhaled is more.
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'.
The respiratory quotient value indicates which macronutrients are being metabolized, as different energy pathways are used for fats, carbohydrates, and proteins. If metabolism consists solely of lipids, the respiratory quotient is approximately 0.7, for proteins it is approximately 0.8, and for carbohydrates it is 1.0.
Some other organic acids and their R.Q. are – Succinic acid (1.14), Taurtric acid (1.6) and Acetic acid (1).
The value of respiratory quotient depends on the type of respiratory substrate. Its value is one for carbohydrates. However, it is always less than one for fats as fats consume more oxygen for respiration than carbohydrates.
Solution. The ratio of the volume of carbon dioxide liberated and the volume of oxygen consumed, during respiration is called Respiratory Quotient (R.Q)
The respiratory quotient (RQ) is the ratio of CO2 produced to O2 consumed, while food is being metabolized. The carbohydrates have equal numbers of carbon and oxygen in their molecules.
