Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).

Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase. Each stage of mitosis is necessary for cell replication and division.
Catalysts increases the rate of a reaction by lowering the need for a larger reaction. Basically, the more reactions that are created, the faster the rate of the reactions will become. An example of this is Amylase in our saliva.
