Cellular respiration takes place in every living organism, and it is the only primary way in which a cell acquires vital energy that fuels any cell function in a living organism. Respiration comprises of a sequence of reactions mainly occurring within living cells mitochondria. Respiration transforms oxygen and the sugars produced by photosynthesis into CO2, water, and energy. Aside from other factors such as plant species, environmental factors are also at play in cellular respiration of a plant cell.
Like most chemical reactions, cellular respiration is greatly influenced by temperature. The respiration rate in a plant cell declines whenever the temperature drops until the cellular respiration almost or completely stops at freezing conditions. This research study indicates that cellular respiration rises with temperature increase until very extreme temps are approached, and tissue dysfunction happens. According to Bruhn (2002), “the temperature sensitivity tends to decrease with increasing temperature and when the temperature approaches the temperature optimum and further exceeds the temperature optimum” (p.121).
The temperature responsiveness of the cell respiration depends on the temperature, species, and growing conditions. Even below the optimal temperature for photosynthesis, an exponential function may be a clearer representation of the temperature sensitivity, and there appear to be feasible fundamental physiological or biophysical processes for a rather sigmoid-shaped temperature correlation. In addition, it is now essential to analyze the mechanisms involved in supposedly lower temperature responsiveness of cellular respiration in the light compared to the dark. Furthermore, this reduced temperature responsiveness of cellular respiration in the sun is necessary to take into consideration the CO2 interchange between plants and the environment during the analysis phase.
