Abstract
The rate of whole leaf photosynthetic carbon fixation is ultimately dependent upon the capacity of ribulose-1,5-bisphosphate (RuBP) carboxylase (RuBPCase) to carboxylate RuBP. This capacity is modulated by the concentration of substrates (RuBP, CO2 and O2), the concentration of enzyme, its activity and the interaction of these factors with environmental conditions. Changes in the photosynthetic rate of a leaf which result from alterations in environmental conditions (i.e. light intensity, O2 concentration) apparently stimulate a cascade of biochemical events which result in a new equilibrium being reached between the capacity of the leaf to generate metabolic intermediates and/or products and its capacity to utilize them. Of considerable interest is the apparent balancing of the in vivo activity of RuBPCase with the potential of the entire photosynthetic apparatus to support a particular rate of CO2 fixation. The mechanisms by which the CO2 fixation capacity of RuBPCase is regulated in response to varying environmental conditions is the subject of the research and discussion presented here.
