why is leg haemoglobin is called oxygen scavenger?

because in our body haemoglobin alone can perform the transportation of oxygen. oxygen binds with haemoglobin & forms oxyhaemoglobin.wen it reaches the tissues it splits.

Hey Nava neetham , leg haemoglobin has nothing to do with the human body.It is a main component of the nodule(small outgrowth in roots of some plants).The enzyme nitrogenase essential for N2 fixation is highly sensitive to oxygen and cannot function under aerobic conditions as oxygen attacks this enzyme.It is the leg haemoglobin(oxygen scavenger-removing oxygen) that provides an anaerobic environment for the functioning of the enzyme nitrogenase.

In plants colonised by Rhizobium, such as alfalfa or soybeans, the presence of oxygen in the root nodules would reduce the activity of the oxygen-sensitive nitrogenase, which is an enzyme responsible for the fixation of atmospheric nitrogen.

Nitrogenase enzyme is very sensitive to O2.So leg haemoglobin keep O2 AWAY FROM THIS

Answer: Leg haemoglobin is a oxygen carrying hemoprotein found in the root nodules of the leguminous plants. ... As, high oxygenconcentration prevents the presence of oxygenwill prevent the activity of enzyme oxygensensitive nitrogenase, which is an enzyme performs the function of fixation of atmospheric nitrogen.

Leg haemoglobin is called oxygen scavenger because ,the enzyme nitrogenase is highly sensitive to molecular oxygen,it requires anaerobic conditions.So,leg haemoglobin present in the root nodules protects the nitrogenase enzyme from oxygen.
I hope it will help you ??????????
