Identify the incorrect statement regarding the polypeptide, Myoglobin. Select one: a. The interaction between Myoglobin and O2 is homotopic in nature as indicated by a Hill coefficient n = : 1 b. Myoglobin is found predominantly in muscle tissue because it facilitates oxygen diffusion. c. The majority of Myoglobin's secondary structure is composed of alpha-helices d. Myoglobin has a higher affinity for oxygen than Hemoglobin e. Myoglobin serves as an oxygen storage protein as suggested by its hyperbolic binding of 02
