Identify the true statements regarding the heme group of myoglobin and hemoglobin. the iron in the heme group can form six bonds. the fifth is with an imidazole ring of a histidine, and the sixth is with oxygen. the globin chains of myoglobin and hemoglobin prevent the oxidation of fe2+fe2+ to fe3+fe3+ , which irreversibly binds oxygen. the cooperativity of oxygen binding in hemoglobin arises from a shorter fe−o2fe−o2 bond length in the t state compared to the r state. a heme group contains four pyrrole rings, which are linked via methene (methine) bridges. the heme group is conjugated. myoglobin contains one heme group. the r state of hemoglobin has greater affinity for o2o2 than the t state because the iron atom is in the plane of the porphyrin ring.

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
