$3\mathrm{.}2)$ Indicate what is true about mechanisms of toxicity $($indicate all that can apply$)$Methemoglobinemia is caused by chemicals that cause electron transfer that oxidizes the Fe in hemoglobin from Fe$2+$ to Fe$3+$Lipid peroxidation is initiated by a reaction to a ROSAn antagonist does not require structural similarity to the natural ligand to block the receptor.Inhibition of oxygen binding to hemoglobin by CO is an example of non covalent binding causing toxicity
