Nowadays, one can easily find calorespiromerty among CSE paper presentation topics related to microbiology or animal physiology, but until recently, calorimetric methods have been employed exclusively for studying plans. Moreover, existing respiration models were limited by lack of measuring methods for the substrate efficiency of carbon conversion in plants. There are large amounts of data related to respiration rates, but only scarce data related to directly measured efficiencies. Some authors claim that single measures of CO2 production and O2 uptake rates are correlated with plant growth rates. But this knowledge still remains insufficient as long as we know little about how the relation between growth and metabolism changes with experimental conditions. It is not possible to find such calculations in books with an algebra homework help.
Calorespiromerty is a convenient method that permits to measure both rate and efficiency of plant metabolism because it allows simultaneous measurement of these parameters as functions of temperature. Although, it requires building a model based on both thermodynamics and plant biochemistry. Otherwise, it would be but nothing special – just one more method for measuring respiration rates, even though an especially useful one. Nevertheless, from writing college application essays to establishing international collaborations any genuine scientist is much stronger interested in an accomplished theory than in a simple enumeration of methods. That is why the usage of calorespiromerty in modern plant physiology tends to develop towards the fundamental understanding of how energy from respiration is employed in moving nutrients and photosynthate into new tissues.
