Question

Leghaemoglobin helps in

Options

A.nitrogen fixation
B.protecting nitrogenase from O2
C.destroys bacteria
D.transport of food in plants

Solution

The root nodules of leguminous plants contain asymboitic nitrogen fixing bacteria Rhizobium. root nodules are small irregular outgrowth of the roots which are pinkish internally due to presence of a pigment calle leghaemoglobin. It is related to blood pigment haemoglobin and coniain polyhedral bacteria called bacteroids. Leghaemoglobin is an oxygen scavenger and protects the nitrogen fixing enzyme nitrogenase of bacteroids.
