Question
ofthe following siatements about hemoglobin and structure are true? myoglobin Select the five true statements. Map Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central atom. Heme is composed of an organic protoporphyrin component and a metal atom. Molecular oxygen binds reversibly to Fe2" in heme. myoglobin molecule can bind four oxygen molecules. O Each hemoglobin or Each iron atom can form six coordination bonds: Two of these bonds are formed between iron and oxygen. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom. Hint A Previous Give up & View Solution Check Answer Next E O Both myoglobin and hemoglobin are globular proteins.

Heme is composed of an organic protoporphyrin component and a metal atom ... TRUE!
Both haemoglobin and myoglobin contains a prosthetic group called heme, which contains a central Fe atom.. TRUE
By itself heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom.. TRUE.
Molecular oxygen binds reversibly to ferrous in heme... Also TRUE
Each haemoglobin can bind 4 oxygen molecules; each myoglobin can bind only 1 oxygen molecule TRUE
FALSE:
Hemoglobin is heterotetramer whereas myoglobin is a monoer, false, myoglobin is not monomer
Each iron atom can form fix coordingation.... False, not only 1 of these bonds but all
So... choose all but the last two
