What substance in the blood controls the rate of respiration?
Carbon dioxide levels in the blood are the main regulator of respiration rate. When CO2 levels increase, the body signals to breathe more rapidly to eliminate excess CO2 through exhalation. Conversely, when CO2 levels decrease, breathing slows down to retain more CO2 in the body.
How does increase of CO2 levels affect photosynthesis?
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
What is the breathing rate determined by the level of something in the blood?
The breathing rate is determined by the level of the carbon bi oxide. The increase in the concentration, increase the breathing rate. The decrease in the oxygen concentration should do the same thing. But the oxygen is poorly soluble. So it can not affect the breathing centre like the carbon bi oxide. The carbon bi oxide is highly soluble and it also alters the pH of the blood.
What is the relationship between increased blood carbon dioxide respiratory rate and depth?
CO2 is the primary cvontrol for rate of breathing (not oxygen as many would expect). High levels of CO2 are very toxid to the tissues of the body and os it was allowed to remain in the blood most of these tissues would die off. And so sensors within the blood systmem detect the CO2 levels and stimulate faster deeper breathing if thesae elvels are to high for safety.
What factors increase or decrease the rate of photosynthesis?
Factors that increase the rate of photosynthesis include higher light intensity, optimal temperature (usually around 25-30°C), and sufficient availability of carbon dioxide and water. Factors that decrease photosynthesis rate include low light intensity, extreme temperatures (too hot or too cold), insufficient carbon dioxide levels, and limited water availability.
What effect would an increase in co2 have on respiratory rate?
respiration rate would increase in order to blow off co2
An increase in the level of carbon dioxide in the blood should decrease the rate of breathing?
No: it would tend to call urgency into your body's systems to do all that can be done to decrease these toxic levels and increase the oxygen levels. This would considerably increase your breathing.
Does increase in blood co2 increase or decrease respiratory rate?
When your oxygen levels go up and carbon dioxide levels in the body go down this will cause your heart rate to speed up. This is caused by the blood vessels opening and the heart working harder to pump the blood.
If your pCO2 is 35 and your pH is 7.35 what would happen if you increase your respiratory rate?
If you are healthy nothing should happen because your body will make the necessary adjustments by increasing the sodium bicarbonate level to keep the pH level normal. If you are sick and you increase your resp rate and your body can't adjust then the pH will go down along with the cO2 level. This is true if the body is given enough time to adjust. However, it takes the renal system 24 - 48 hours to adjust to changes in the CO2 levels. In the short run, if you increase respiratory rate, the CO2 level will decrease and the pH will increase. This can lead to a respiratory alkalosis.
When blood CO2 levels increase does the pH increase or decrease?
When blood CO2 levels increase, it leads to an increase in hydrogen ion concentration, which lowers pH, making it more acidic. This phenomenon is known as respiratory acidosis.
What substance in the blood controls the rate of respiration?
Carbon dioxide levels in the blood are the main regulator of respiration rate. When CO2 levels increase, the body signals to breathe more rapidly to eliminate excess CO2 through exhalation. Conversely, when CO2 levels decrease, breathing slows down to retain more CO2 in the body.
Why can CO2 exhalation be used as a measure of respiratory rate in humans?
CO2 exhalation can be used as a measure of respiratory rate in humans because as we breathe out, we release CO2 which is a byproduct of cellular metabolism. This exchange of gases reflects the rate at which our body is producing and releasing CO2, which is directly related to our respiratory rate. By measuring the level of CO2 exhaled, we can determine how effectively our respiratory system is working.
What is the relationship between increased blood co2 and respiratory rate and depth?
The higher the respiratory rate and deeper the breaths the lower the blood CO2.
Does the increase or decrease of CO2 affect the pH level?
Yes, the increase of CO2 can decrease the pH level of a solution, leading to acidification.
Did it appear that CO2 or O2 had a greater effect on modifying the respiratory rate?
CO2
How does hypoventilation affect respiratory rate?
It is due to CO2 reduction. Low CO2 stimulates chemo-receptors in brain stem. Respiratory rate is reduced in order for CO2 to come back to normal.
How does increase of CO2 levels affect photosynthesis?
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
