Question

Name the oxygen scavenger present inside the root nodules of leguminous plants

Answer 1

rhizobia

Answer: Leg haemoglobin is a oxygen carrying hemoprotein found in the root nodules of the leguminous plants. It is produced in response to the roots being colonized by nitrogen- fixing bacteria called as rhizobia.

Answer 2

Leghaemoglobin is an oxygen-transporter particle. It safeguards nitrogen-fixing protein nitrogenase from the symptom of oxygen

Leghaemoglobin

• The chemical nitrogenase is exceptionally delicate to the sub-atomic oxygen; it requires anaerobic circumstances. The nodules have variations that guarantee that the chemical is safeguarded from oxygen.
• To safeguard these proteins, the root nodules contain an oxygen forager called leg-haemoglobin.

• Leguminous plants are in a cooperative relationship with nitrogen-fixing microbes like Rhizobium.
• These microbes attack root hairs of leguminous plants and structure root knobs in which they fix nitrogen. A red shade present in the root knobs of leguminous plants is known as leghaemoglobin. Leghaemoglobin is an oxygen-transporter particle.
• It safeguards nitrogen-fixing protein nitrogenase from the symptom of oxygen as the compound is profoundly delicate to oxygen.
