Question

Write R.Q. for carbohydrates, fats, and proteins?

Answer 1

Hint: R.Q. is respiratory quotient it is a dimensionless number used in the calculation of the basal metabolic rate. The ratio of carbon dioxide emitted by the body to oxygen absorbed by the body is used to measure it.

Complete answer:
The respiratory quotient (RQ) is the ratio of the carbon dioxide produced to oxygen consumed while the food is being metabolized. The respiratory quotient of carbohydrates is $$1$$. The respiratory quotients are the ratio where carbon dioxide is removed from the body. The ratio of carbon dioxide emitted by the body to oxygen absorbed by the body is used to measure the respiratory quotient. Measurements like oxygen uptake are indirect calorimetry, this is measured using a respirometer. The RQ indicates which macronutrient is metabolized, as different energy pathways are used for fats, carbohydrates, and proteins. If the metabolism consists of fats the RQ is about $$0.7$$, for proteins, it is about $$0.8$$, and for carbohydrates, it is $$1.0$$. Energy consumption is anyways composed of both fats and carbohydrates. In order to calculate the basal metabolic rate, a dimensionless number is used.

Additional information:
The practical application of the respiratory quotient can be found in the case of chronic obstructive pulmonary disease. In this case, the patient spends a lot of energy on respiratory efforts. The respiratory quotient is used as an indicator of over or underfeeding. The significance of the respiratory quotient is that it is used for the calculation of basal metabolic rate (BMR).

Note:
R.Q. is the respiratory quotient. The respiratory quotient (RQ) is used to measure the basal metabolic ratio. The respiratory quotient is defined as the volume of carbon dioxide released over the volume of oxygen. The respiratory quotient can be calculated using the formula RQ = $$C{O}_2$$ eliminated $$/O2$$ consumed. The value of RQ for carbohydrates is $$1.0$$, fir fats are $$0.7$$ and in protein, it is $$0.8$$.
