Question- Neuroglobin is a member of the globin family found in neurons. It is a monomeric protein that helps protect the brain from hypoxia (low O2). Identify the correct statement(s) about neuroglobin below.
a) It binds O2 with a hyperbolic binding curve.
b) It binds O2 with a sigmoidal binding curve.
c) It binds O2 with higher affinity than hemoglobin.
d) It binds O2 with lower affinity than hemoglobin.
