the control of respiration rate.

English:
The respiration rate is a parameter which is used in ecological and agronomical modelling. In theoretical production ecology and aquaculture, it typically refers to respiration per unit of time (usually loss of biomass by respiration per unit of weight), also referred to as relative respiration rate. In theoretical production ecology, biomass is expressed as dry weight, in aquaculture as wet fish weight. The respiration rate is dependent of species, type of tissue or organ studied and temperature.


The respiration rate determines which proportion of the primary production can be invested in growth and harvest products and thus directly influences production figures.

not enzyme. the nerve cells in "medulla" the hind brain. detecting it from CO2 concentration in blood.

rate of respiration is determined by the energy demand of your body
