Glucagon increases blood glucose very quickly by activating phosphorylase. This is very efficient because phosphorylase: A.is a G-protein. B.reduces cyclic-AMP. C.has phosphodiesterase activity. D.cleave the 1-6 branches. E. acts at multiple 1-4 endings.

Suppose myoglobin is prepared with Zn²+ in the place of Fe²+ in the porphyrin. Would you expect this modified myoglobin to bind oxygen? No, because Zn²+ cannot partially transfer an electron to oxygen to form a complex. Fe²+ . Yes, because oxygen can form a bond with either Zn²+ 2+ No, because the larger size of Zn²+ will prevent the ion from fitting within the porphyrin ring. Yes, because oxygen binding to myoglobin depends solely on the presence of a distal histidine. or
