Concept explainers
Interpretation:
The relative rate of incorporation of CO2 by Rubisco under N2 and under pure O2 should be described. It should also be decided if O2 is competitive or uncompetitive inhibitor.
Concept introduction:
In any enzyme, the activity can be inhibited if any small molecule or ion is bonded to it. This inhibition can be done either irreversibly or reversibly.
The competitive inhibitors can resemble with the substrate and so they bind to the active sites of enzyme while the uncompetitive inhibitors do not bind as substrate but it binds to enzyme site simultaneously with substrate. The uncompetitive inhibitors are reversible in nature.
When the concentration of competitive inhibitor increases, the higher concentration of substrate is required while in case of uncompetitive inhibitors the concentration of substrate does not increase.
Pictorial representation:
From the given data; the relative rate of incorporation of CO2 by Rubisco under N2 and under pure O2 could be given as:
