The molecule known as coenzyme A plays a key role in cell metabolism by regulating the actions of nitric oxide. Coenzyme A sets into motion a process known as protein nitrosylation, which unleashes nitric oxide to alter the shape and function of proteins within cells to modify cell behavior.
Reticular formation plays this role.
