7. Nitric oxide (NO) is an important player in immune response to microbial invasion and it is a neurotransmitter. Its formation from the amino acid arginine is catalyzed by a metalloenzyme called nitric oxide synthase. Nitric oxide forms ON(02)-, a potent inducer of oxidative stress, in a diffusion controlled reaction with superoxide (Of). Draw reasonable NO schemes for NO and 02 , with careful attention to relative AO and MO energies. Predict bond orders and magnetic properties.
