Vedclass · Answer

(D) Nitrogen fixation by $Rhizobium$ in the root nodules of leguminous plants is a complex biochemical process. This process is highly sensitive to the presence of oxygen. $Rhizobium$ produces an oxygen-scavenging pigment called $leghemoglobin$ (often referred to as the 'oxygen buffer'). $Leghemoglobin$ maintains a low oxygen concentration in the nodules,which is essential for the activity of the enzyme $nitrogenase$. Since none of the options (Potassium,Nitrogen,Phosphorus) directly stimulate the fixation process in the context of the question's focus on essential environmental factors,the correct answer is $D$.

The process of nitrogen fixation by $Rhizobium$ is stimulated by the presence of which of the following?
