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.
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.
The average ratio of pulse rate to respiration rate is typically around 4:1.

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.
Respiration in humans is controlled by medulla, which is a part of the brain. The medulla is responsible for the provision of adequate amount of oxygen for every activity. Medulla sends signals to our body to provide oxygen for every activity like sleeping, eating, walking, exercising etc. Human brain measures the level of carbon dioxide in blood and makes necessary adjustments to balance the amount of oxygen and controls respiration rate. Breathing is controlled by the brain but it can be controlled voluntarily also like holding ones breath. But this is just temporary and the medulla takes charge again after a few minutes to restore the breathing
