A firefly glows by the direct conversion of chemical energy to light. The light emitted by a firefly has peak intensity at a wavelength of \(550 \mathrm{~nm}\).

a. What is the minimum chemical energy, in \(\mathrm{eV}\), required to generate each photon?

b. One molecule of ATP provides \(0.30 \mathrm{eV}\) of energy when it is metabolized in a cell. What is the minimum number of ATP molecules that must be consumed in the reactions that lead to the emission of one photon of \(550 \mathrm{~nm}\) light?
