What is the respiratory quotient in simple terms?

The respiratory quotient, also known as the respiratory ratio (RQ), is defined as the volume of carbon dioxide released over the volume of oxygen absorbed during respiration. It is a dimensionless number used in a calculation for basal metabolic rate when estimated from carbon dioxide production to oxygen absorption.

What is the best definition of respiratory quotient quizlet?

A measure of the ratio of carbon dioxide produced and oxygen consumed by an organism per unit of time. Respiration.

What is the importance of respiratory quotient?

(i) R.Q. helps in determining the type of respiration being performed. (ii) R.Q. gives some information about the significant transformation of food materials.

Why RQ of fat is less than 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.

What is the RQ for aerobic respiration of glucose?

The respiratory quotient (RQ) for yeast respiring aerobically and using glucose as a substrate is 1.0.

What is the efficiency of anaerobic respiration?

Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration.

Is a high respiratory quotient good?

In summary, the current study has found that a high RQ is predictive of gains in body weight and fat mass over a 12-month period among young adults when compared with individuals with a low/moderate or low-RQ value.

Why is respiratory quotient less than 1?

When respiratory quotient (RQ) is less then one in a respiratory metabolism, it means that respiratory substrate is either fat or protein.

What is a good respiratory quotient?

Your respiratory quotient is a decimal between 0.7 and 1.0. A normal range is typically around 0.8 – 0.85. The results may also be broken down by macronutrients to represent how much of each substrate your body is deriving its energy from.

Why is respiratory quotient important?

Significance of Respiratory Quotient (i) R.Q. helps in determining the type of respiration being performed. (ii) R.Q. gives some information about the significant transformation of food materials.

What is the difference between aerobic and anaerobic respiration?

Aerobic Respiration — Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.

How many ATP is produced in anaerobic respiration?

2 ATP molecules
Anaerobic respiration results in the production of 2 ATP molecules.
