myoglobin: the molecule is compact there is no water inside it with the exception of a very small number(less than 5) of single water molecules presumably trapped at the time the molecules is folded up.
hemoglobin: it iz 4 times larger than myoglobin. it is spherical molecule formed by 4 subunits which are identical in pairs . each subunits has a conformation closely resembling that of myoglobin and the aggregation is held together by extensive van der waals forces.
Cooperative binding. Hemoglobin can load and unload oxygen better than myoglobin. So it is kore sensitive to changes in the environment, vs. Myoglobin
Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body, while myoglobin is a protein found in muscle cells that stores oxygen for muscle use. Hemoglobin has a higher oxygen affinity and is responsible for transporting oxygen, whereas myoglobin releases oxygen for muscle metabolism when needed.
iron. thanks for this quick answer.
Myoglobin
Myoglobin and hemoglobin are structurally similar proteins, with around 20% sequence similarity. They both contain heme groups that bind oxygen, but hemoglobin is found in red blood cells and is responsible for transporting oxygen, while myoglobin is found in muscle tissue and is involved in storing and transporting oxygen within muscles.
Keratin and collagen are fibrous proteins, providing structural support and strength to tissues like hair and skin. Myoglobin and hemoglobin are globular proteins, designed for carrying and binding molecules like oxygen in the blood. The difference in their structures reflects their specific functions in the body.
Myoglobin's function is similar to that of hemoglobin, which carries oxygen in red blood cells to various tissues. Myoglobin has even higher affinity for oxygen than hemoglobin and is specific to muscle cells. Myoglobin thus acts as a storage of oxygen, as it holds oxygen inside heart and skeletal muscles.
keratinThe correct answer is NOT keratin... the correct answer is myoglobin. This is the oxygen-binding pigment in muscle.
The iron-containing protein found in red blood cells that carries oxygen from the lungs is called hemoglobin. It is responsible for binding to oxygen in the lungs and transporting it to tissues throughout the body.
An iron-containing protein is called a heme protein, which includes hemoglobin and myoglobin. These proteins are crucial for transporting and storing oxygen in the body.
1 Each myoglobin molecule has one heme group and can bind one oxygen molecule. Hemoglobin on the other hand can bind up to 4 molecules of oxygen.
Hemoglobin is the protein inside red blood cells that binds with oxygen. It consists of four protein subunits, each containing a heme group that can bind to oxygen molecules.
