Question

What is the rq value when potato is consumed and oxidized during respiration?

Answer 1

RQ value of a potato is one.

•Respiratory quotient or RQ is defined as "the ratio of carbon dioxide produced to the oxygen consumed."

•Since respiratory quotient is a ratio, It has no units.

•Potato has the main constituent as starch.

•It is a carbohydrate and a homopolymer of glucose.

•Respiratory quotient value of carbohydrates is one.

•This means, for carbohydrates amount of carbon dioxide produced is equal to the amount of oxygen required.

•Example -

C6H12O6 + 6O2 -> 6CO2 + H2O

Thus, 6CO2/6O2 = 1

Thus, the respiratory quotient is one.

Answer 2

Respiratory Remainder Value of Carbohydrates

Explanation:

1. The respiratory substrate is sugars, it gets totally oxidized. Therefore, the measures of oxygen and carbon dioxide become equivalent.
2. The respiratory remainder (RQ), characterized as the proportion of carbon dioxide breathed out to oxygen take-up, reflects substrate use when vitality is used.
3. Fat and liquor have RQ estimations of about 0.7, contrasted with 1.0 for starch, and about 0.8 for protein.  
4. At the point when starches are totally oxidized during breath, the RQ is 1. The term RQ alludes to Respiration Quotient and is a dimensionless amount.
5. It is characterized as the proportion of the volume of carbon dioxide developed to the volume of oxygen devoured.  
6. For glucose, with the atomic recipe, C6H12O6, the total oxidation condition is C6H12O6 + 6 O2 → 6 CO2+ 6 H2O. In this way, the RQ= 6 CO2/6 O2=1.  
7. "Respiratory remainder is the proportion of CO2 created to O2 devoured while nourishment is being used." When breath utilizes fats, the RQ turns out to be under 1.
