How can proteins be used as a respiratory substrate?
How can proteins be used as a respiratory substrate?
When supplies of carbohydrate and lipid are inadequate, the body can use protein as a respiratory substrate- in times of prolonged starvation, tissue protein from muscles can even be broekn down for this purpose. The proteins are hydrolysed into their constituent amino acids, which are then deaminated in the liver.
What are proteins used for in respiration?
Abstract. Respiratory proteins enhance the capacity of the blood for oxygen transport and support intracellular storage and delivery of oxygen. Hemocyanin and hemoglobin are the respiratory proteins that occur in the Pancrustacea.
In which of the following respiration protein is used as respiratory substrate?
Primary respiratory substrate is carbohydrate, secondory respiratory substrate is fat, tertiary respiratary substrate is protein.
Do proteins help with respiration?
When proteins are used in the cellular respiration pathway, they are first broken down into individual amino acids. These intermediates enter cellular respiration at various places in the Citric Acid Cycle (Figure 2).

How to determine the type of respiratory substrate?
Carbohydrates: RQ = 1.0 Proteins: RQ = 0.9 Lipids: RQ = 0.7 By measuring the oxygen consumed and carbon dioxide released at each stage of respiration, the type of substrate can be determined. By removing carbohydrates, weight can be lost quickly, but there are problems cutting out molecules commonly used for food…
What are the substances that take part in respiration?
In respiration carbohydrate, protein, fat, organic acid etc. are oxidize and produce energy. The substances which take part in respiration are known as Respiratory substrate. Respiration occurs in cytoplasm and mitochondria of a living cell. There is no definite time for respiration. This process runs 24 hours throughout the day and night.
What is the respiratory quotient of a molecule?
Different Respiratory Substrates A respiratory substrate is any organic molecule broken down to release energy for the synthesis of ATP. The respiratory quotient of a substrate is the ratio of CO2 to O2 produced/consumed to break down that molecule.
