The partial pressure of oxygen (O2) determines how much oxygen can be delivered from the lungs to the blood. At higher altitudes the partial pressure of oxygen is lower and it is therefore harder to extract the oxygen from the air to bind with the hemoglobin. Because of the oxygen deficit as compared to sea level breathing rate increases.
The primary stimulus to respiration is the level of C02 in the brain. As C02 rises the drive to increase the rate of breathing is increased. As that rate increases the levels of C02 within the blood decrease and the drive is depressed. This is called a feedback response loop. In addition very low levels of oxygen in the blood can also increase the drive to respiration but unless you are climbing a very high mountain it isn't normally relevant.
in humans there are receptors in the brain which monitor CO2 levels, when they are too high the brain issues an order to take a breath
it's not. its a reflex
Breathing is the mechanical procedure in which air reaches the lungs. The rate of respiration is controlled by a respiratory center in the brain stem that responds to changes in the hydrogen ions and carbon dioxide in the blood.
The respiration rate is your breathing rate and your pulse rate is your heart beat.
respiration is but photosynthesis isn't.
The respiration rate is the number of breaths taken in 1 minute.

The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.

A pig's normal respiration rate is between 20 and 40 breaths per minute. This respiration rate is normal for pigs that are still eating and growing.
Carbon bi oxide is powerful stimulant for the respiration. Increase in carbon bi oxide increase the rate of respiration. Decrease in carbon bi oxide decease the rate of respiration.
the respiration rate goes up because the energy required by the cell cannot be provide by the normal rate of respiration
