<prompt> Which of the following statement is true regarding Cyanide ?Only minimally inhibits the ETC because cytochrome oxidase is the terminal component of the chainInhibits mitochondrial respiration but energy production is unaffectedAlso binds the copper of cytochrome oxidaseBind to Fe of cytochrome a3  <response>: That is why methhemoglobin is an effective antidote since it also has Fe.Respiration and energy production is the coupled process, so inhibition of one inhibits the other as well.Cu is an important part of cytochrome oxidase, but cyanide does not bind it.
