The most prominent of these (and historically the first) is the representation theory of groups, in which elements of a group are represented by invertible matrices in such a way that the group operation is matrix multiplication.
hemoglobin is able to perform this function due to its ability to reversibly bind to oxygen. inside oxygen rich areas of the lungs, hemoglobin picks up oxygen molecules, then it transports the oxygen via red blood cells to bodys tissue, once hemoglobin reached the oxygen poor area of the tissues it releases the oxygen.
Therefore, one molecule of hemoglobin can bind four molecules of oxygen. As each red blood cell contains about 280 million hemoglobin molecules, a single red blood cell can carry over 1 billion molecules of oxygen. Once again, that's a lot of oxygen! Cooperative Binding. Okay, so hemoglobin carries oxygen, but how does oxygen bind to hemoglobin? The way by which hemoglobin binds oxygen is referred to as cooperative binding. The binding of oxygen to hemoglobin makes it easier for more oxygen to bind. Let's consider an analogy.
