The central chemoreceptors will increase their firing rate in direct response to increases in the level of in the CSF resulting in ventilation?
carbon dioxide; increased
What is respiration from the organ level to the cellular level?
According to my knowledfe Photorespiration is the respiration from the organ level to the cellular level.
Type of respiration that does not require oxygen.?
This is anaerobic respiration, also called fermentation or substrate level phosphorylation
Does light affects cellular respiration in algae?
Yes, actually. Algae at different depths below sea level have adapted over time to use the available light for cell respiration.
How the carbon dioxide in blood regulate the respiration?
when co2 levels build up in your circulation ,, blood pH is reduced [more acidic] and that triggers chemical receptors in certain areas of your blood vessels ,and these receptors send signals to the respiratory center [at medulla oblongata] to increase rate of respiration to flush away these accelerated levels through air in your exhalations
The central chemoreceptors will increase their firing rate in direct response to increases in the level of in the CSF resulting in ventilation?
carbon dioxide; increased
Does an increase in carbon dioxide levels cause an increase in depth of breathing?
The answer is 'yes'. Increase in carbon bi oxide level directly stimulates the respiratory center and it is the most powerful stimulation for respiration. So, it increases the depth and rate of respiration and rate of respiration, in order to get rid of carbon bi oxide.
What is respiration from the organ level to the cellular level?
According to my knowledfe Photorespiration is the respiration from the organ level to the cellular level.
Does the CNS respiration center analyze oxygen levels of blood?
Oxygen is very sparingly soluble. Carbon dioxide is highly soluble in water or plasma. The respiratory center is stimulated by high level of the carbon dioxide. The respiratory center probably does not analyse the oxygen level.
Why does exposure to carbon dioxide increase the rate of breathing?
When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid. Lactic acid produced by anaerobic exercise also lowers pH. The drop in the blood's pH stimulates chemoreceptors in the carotid and aortic bodies in the blood system to send nerve impulses to the respiration centre in the medulla oblongata and pons in the brain. These, in turn send nerve impulses through the phrenic and thoracic nerves to the diaphragm and the intercostal muscles, increasing the rate of breathing. Even a slight difference in the bloods normal pH, 7.4, could cause death, so this is an important process.
What happens when you hold your breath?
Carbon dioxide and water are a by product of cellular metabolism. They combine to make H2CO3, carbonic acid. This acid circulates in your blood and reaches your cerebral spinal fluid. There are central chemoreceptors for hydrogen ion concentration that monitor the pH level of your cerebral spinal fluid. (the carbonic acid has hydrogen ions) Normally you would exhale these hydrogen ions during respiration. But, you are holding your breath. The build up of carbonic acid causes your cerebral spinal fluid acid level to lower. The central chemoreceptors for hydrogen ion concentration in your cerebral spinal fluid excite the inspiratory center of the medulla. The medulla exerts autonomic control over the lungs via the inspiratory center. You will inhale when these levels increase to a level where this autonomic control center takes over. Hope this helps. It's all physiology and chemistry.

Which of these does not affect the cholesterol level?
-respiration
How do you increase level of androgen in males?
First of all, there is no such way to increase androgen level in your blood but production can be stimulated by masturbating at least three to four times a week. In many cases this has been to prove effective. Besides masturbating, yoga is another effective method for stimulating androgen production in your body. Androgens give you male sex charestirictics
Why do peripheral chemoreceptors only detect a drop in PO2 below 60 mmHg?
Because they are less sensitive to small decreases in arterial Po2 level.
Which of these does not affect a persons cholesterol level?
respiration
What does respiration mean at the organism level?
okkkkkkkkk
