Question

name the enzyme found in root nodules for N2 fixation name the pink colour pigment required for the functioning how does this pigment protects the enzyme​

Answer 1

The pink color is from l-e-g-h-e-m-o-g-l-o-b-i-n, a protein that carries oxygen—similar to the hemoglobin in human blood. The n-i-t-r-o-g-e-n-a-s-e enzyme involved in N fixation is sensitive to oxygen and the l-e-g-h-e-m-o-g-l-o-b-i-n helps reduce oxygen concentrations in the area of the nodule where the

n-i-t-r-o-g-e-n-a-s-e enzyme is active.

if u like it than rate it

Answer 2

Answer:

nitrogenase,

the pink colour pigment is leghaemoglobin for its functioning

this pigment helps in scavenging oxygen as nitrogenase function under anaerobic conditions
