Which metal is present in myoglobin?

The metal present in myoglobin is (d) Iron. Myoglobin is a protein primarily found in muscle tissues, particularly in skeletal and cardiac muscles. It plays a crucial role in oxygen storage and transport within muscle cells. Each myoglobin molecule contains a single iron ion (Fe2+) at its core, which binds reversibly to oxygen molecules, facilitating their storage and release as needed during muscle contraction and metabolic activities. This iron ion is essential for the protein’s function, enabling it to efficiently capture oxygen from the bloodstream when oxygen levels are high and release it when oxygen demand increases during muscle activity. Without this iron ion, myoglobin would not be able to perform its vital role in supplying oxygen to muscle tissues, which is essential for energy production and overall muscle function.
