Describe the role of chloroplast pigments in light absorption

A light-capturing unit in a chloroplast’s thylakoid membrane has two molecules of P700 chlorophyll a at its reaction center. (It is called P700 because it most effectively absorbs light of wavelength 700 nm).Group of answer choicesrubiscoreaction-center complexPEP carboxylaseprimary electron acceptorphotosystemNext

A light-capturing unit in a chloroplast’s thylakoid membrane that has two molecules of P680 chlorophyll a at its reaction center. (It is called P680 because this pigment is best at absorbing light having a wavelength of 680 nm).Group of answer choicesrubiscoreaction-center complexprimary electron acceptorphotosystemPEP carboxylaseNext
