MUSCLE PHYSIOLOGY

Detailed explanation-1: -Myoglobin is a red-colored oxygen-containing pigment found in muscle. It’s related to the pigment hemoglobin, which stores oxygen in blood cells.

Detailed explanation-2: -Due to the presence of heme moiety, myoglobin serves as a carrier and store for oxygen in muscle cells of the body.

Detailed explanation-3: -Hemoglobin is a heterotetrameric oxygen transport protein found in red blood cells (erythrocytes), whereas myoglobin is a monomeric protein found mainly in muscle tissue where it serves as an intracellular storage site for oxygen.

Detailed explanation-4: -Myoglobin is a heme protein that acts as an oxygen carrier in muscle cells and is responsible for the color of both raw and cooked meat. The amount of myoglobin varies between different muscle types.

Detailed explanation-5: -Myoglobin is an oxygen binding protein present in all muscle fibers. It is an airon-containing protein similar to haemoglobin and gives the muscle a reddish appearance. Red muscle fibres have abundant myoglobin while white muscle fibers have less myoglobin.
