Question

O A Hemoglobin is present in red blood cells O B Myoglobin is abundant in mammalian muscle tissue. C Myoglobin is a tetrameric protein with four protein subunits. O D Hemoglobin has four identical protein subunits-each designated as alpha (a) O E Hemoglobin and myoglobin both contain the prosthetic group heme. OF Hemoglobin utilizes a bound zinc (Zn2+) ion to bind oxygen O GHemoglobin can bind four molecules of 2 3-bisphosphoglycerate- one to each protein subunit O H Hemoglobin can bind four molecules of 02. OIHemoglobin contains a single heme that is buried at the interface between four protein subunits. O J Hemoglobin is found predominantly in muscle cells and serves as an oxygen storage protein.
