How many oxygen molecules can myoglobin carry
WebBecause hemoglobin has very different O 2 -binding properties, however, it is not simply a “super myoglobin” that can carry four O 2 molecules simultaneously (one per heme group). The shape of the O 2 -binding curve of myoglobin can be described … WebMyoglobin is closely related to hemoglobin, which consists of four myoglobin-like subunits that form a tetramer and are responsible for carrying oxygen in blood. In humans, blood-borne cardiac myoglobin can serve as a biomarker of heart attack, since blood myoglobin levels rise in two to three hours following muscle injury...
