What is the respiratory quotient What does the respiratory quotient reflect

Respiratory Quotient Respiratory Quotient.

Respiratoryquotient (RQ) refers to the molecular ratio of CO2 released by respiration to O2 absorbed. When sucrose, glucose.

or carbohydrates such as starch.

When used as respiratory substrates, if they are completely oxidized, the oxygen consumption of the cell and the amount of CO2 released are equal, i.e., the RQ value is approximately equal to 1. For example, the Rq of leaves of many plants is about 1 when cereal seeds or other starchy seeds germinate. When some oily and fatty seeds germinate, the rq is about.

When oil or fat is used as a substrate for respiration, a large amount of O2 is consumed. The equation can be completely oxidized by respiration substrates.

to calculate the respiratory quotient. Respiratory quotient for example.

c6h12o6+6o2→6co2+6h2o

Six-carbon sugar RQ 6 6 1

2c57h104o9+157o2→114co2+104h2o

Castor oil. rq＝114/157＝

By measuring the RQ of different tissues or organs of the plant, it is possible to determine the type of respiratory substrate. However, respiratory quotients are often further complicated by many other factors. For example: anaerobic respiration.

, there is no O2 absorption, only CO2 release, and the RQ value is infinity.

When the transformation of substances occurs in the plant body, and the intermediate products of respiration are used for the biosynthesis of other substances, the RQ value will be affected; In plants, a variety of respiratory substrates often respire at the same time, and their respiratory quotient is actually the overall result of the amount of O2 consumed by the cells and the amount of CO2 released when these substances are oxidized. In addition, some physical factors, such as the impermeability of the seed coat, make it difficult to obtain true data on the amount of O2 consumed and the amount of CO2 released during seed germination, so the confidence in the measured RQ value is low.

Respiratoryquotient (RQ) refers to the ratio of the volume or molar number of carbon dioxide released to the oxygen absorbed by an organism at the same time, that is, the molecular ratio of CO2 released by respiration to O2 absorbed.

The ratio of oxygen exhaled to carbon dioxide exhaled by an organism over a given period.

The respiratory quotient reflects the molecular ratio of CO2 released and O2 absorbed by respiration.

A respiratory quotient is an organism that releases carbon dioxide at the same time.

The ratio to the volume or moles of oxygen absorbed refers to the molecular ratio of CO2 released by respiration to O2 absorbed.

This rarely happens in living organisms, so the respiratory quotient measured is actually a non-protein respiratory quotient that is disturbed, i.e. with sugars and lipids.

The respiratory quotient is determined when it is a substrate for oxidative decomposition. However, there is also a difference in the respiratory quotient values of sugars and lipids.

Glycemic index (GI): also translated as glycemic index.

Indicates that it contains 50g of valuable carbohydrates.

food with a considerable amount of glucose.

This compares to the percentage value of the level of blood glucose response in the body that causes it within a certain period of time (usually 2 hours after a meal).

GI is a measure of postprandial blood sugar caused by food.

A physiological parameter of reaction that accurately reflects the physiological state of the human body after ingestion of food. Foods containing the same amount of carbohydrates have different digestion and absorption laws and glycemic responses: high GI foods are digested quickly and have a high absorption rate after entering the gastrointestinal tract, while glucose is injected into the gastrointestinal tract and cause high blood sugar peaks; The opposite is true for low-GI foods.

The molecular ratio of CO2 released by respiration to O2 absorbed.

The respiratory quotient is the ratio of the volume or moles of carbon dioxide released to the oxygen absorbed by an organism at the same time, that is, the molecular ratio of CO2 released by respiration to O2 absorbed.

Due to the different energy supply sequences of sugars, lipids, and proteins, oxidative energy supply of proteins occurs only when both sugars and lipids are insufficient.

This rarely happens in living organisms, so the respiratory quotient measured is actually a non-protein respiratory quotient, that is, the respiratory quotient measured when sugars and lipids are used as substrates for oxidative decomposition. However, there is also a difference in the respiratory quotient values of sugars and lipids.

Plant. When carbohydrates such as sucrose, glucose, or starch are used as respiratory substrates, if they are completely oxidized, the oxygen consumption of the cell is equal to the amount of CO2 released, i.e., the RQ value is approximately equal to 1.

For example, the Rq of leaves of many plants is about 1 when cereal seeds or other starchy seeds germinate. When some oily and fatty seeds germinate, the rq is about. When oil or fat is used as a substrate for respiration, a large amount of O2 is consumed.

Lead blindness and the respiratory quotient can be calculated by the equation for complete oxidation of the respiratory substrate.

Abstract: Answer: Due to the different energy source substances contained in different foods, the aerobic demand and the volume of CO2 generated during oxidation in the body are also different, and the ratio of the volume of CO2 produced by the oxidation of food in the body to the volume of oxygen consumed at the same time is called the respiratory quotient.

rq）。Sugars, lipids.

The respiratory quotient of protein and protein is 7 and 0 8 respectively, and the respiratory quotient is about 0 85 when eating a normal diet, so the respiratory quotient of polysaccharides increases, and if the body uses and consumes lipids and proteins more, the respiratory quotient decreases. The normal respiratory quotient cannot be higher than 1 0 and cannot be countered by 0 7.

The respiratory quotient is the ratio of the volume or molar number of carbon dioxide released to the oxygen absorbed by an organism at the same time, that is, the molecular ratio of CO2 released by respiration and absorbed reflux O2.

Due to the different energy supply sequences of sugars, lipids and proteins, oxidative spring destruction of proteins will occur only when the energy supply of sugars and lipids is insufficient.

This rarely happens in living organisms, so the respiratory quotient measured is actually a non-protein respiratory quotient, that is, the respiratory quotient measured when sugars and lipids are used as substrates for oxidative decomposition. However, there is also a difference in the respiratory quotient values of sugars and lipids.

The explanation of the word breath quotient is: breath quotient hūxīshāng. (1) The ratio of the amount of carbon dioxide released to the amount of oxygen consumed in a given time.

Respiratory quotient Respiratory quotient is the ratio of the volume or number of moles of carbon dioxide released to the oxygen absorbed by an organism at the same time, that is, the molecular ratio of CO2 released by respiration and O2 absorbed.

Verses about the respiratory quotient.

Idioms about respiratory quotients.

Knock on the bone and suck the marrow, breathe the breath is connected, the meal Xia sucks the dew, the geng is breathed together, and the fate is breathed together, such as participating in business, Hao, Shang, Jia, Shang, Yi, Xia Ding.

Words about respiratory quotients.

Inhaling the wind and drinking the dew businessman Yi Xia Ding Dining Xia sucking the dew between the breathing of the wealthy businessmen and giants knocking on the lead cherry blossom bone marrow sucking new vomit, so the vampire moves like a businessman, shouting and singing, and does not suck it.

When the animal is hungry, the fat is broken down first, so the respiratory quotient.

It will go down, from mixed food to fat or so. After long-term starvation, the fat is exhausted and the protein is consumed. Therefore, the respiratory quotient rises again, from the upper auspicious fat to the early white matter of the egg Lu Yan.
