Why does Fe2+ not fit perfectly into the center hemoglobin's heme pocket, while Fe3+ does ift perfectly into center hemoglobin's heme pocket? A) Fe2+ has a larger effective nuclear charge than Fe3+ . B) Fe2+ is to reactive to stably fit into hemoglobin's heme pocket. C) Fe2+ had a wrinkled shirt D) Fe2+ is repelled by the heme's coordinating nitrogens E) Fe3+ is denser and has a smaller ionic radius than Fe2+
