Nov 28, 2016· Introduction. In aerobic respiration, CO 2 is produced and O 2 is consumed. Such respiration occurs in a tree stem’s living cells (, in the phloem, cambium and living parenchyma of the xylem), while CO 2 diffuses out and O 2 diffuses into the respiration site. The respiratory quotient (RQ) is defined as the ratio of the number of molecules of CO 2 released to that of O 2 molecules ...

1. Introduction. The amount of CO 2 produced in the mitochondria is mainly related to the metabolic rate and the quantity of food metabolized. Optimal cellular functioning depends on an adequate supply of oxygen and an appropriate amount of CO 2 to maintain an acidbase balance. Arterial partial pressure of CO 2 (paCO 2) is an indicator of the body’s ventilation status.
