Red blood cells contain approximately 270 million hemoglobin molecules, each of which has four heme groups. Therefore, the total number of heme groups in a single red blood cell is around 1.08 billion. Hemoglobin is responsible for transporting oxygen throughout the body, with the heme groups playing a crucial role in binding oxygen molecules.
Four heme groups, so I think four molecules of oxygen can be transported by one molecule of haemoglobin.
4 molecules of oxygen - one to each subunit on the heme
it is two main groups
There are over 30 blood groups for horses, 8 of these are major groups and 7 are recognized internationally.
There are two well known types of "blood colors". The color of the blood is closely related to the oxygen molecules. O2 molecules can be bound in different ways: by the ferrous heme groups of the globins (e.g., myoglobin and hemoglobin); or by two Cu+ ions held in close proximity by six His side chains in hemocyanins. Fe2+ and Cu+ ions and ferrous heme groups free in solution do not bind reversibly; instead, they oxidized to the Fe3+ and Cu2+ forms. Under these circumstances, when Fe2+ is oxidized to Fe3+ acquires a red color, this is the reason why blood is red in upper organisms, those that have hemoglobin. On the other hand, when Cu+ oxidizes to Cu2+ turns to blueish color. In lower organisms (e.g., crustacea) the blood turns blueish when is exposed to oxygen. In resume, we have two blood colors, red and blueish, when it's oxidized.
There is only one normal type of red blood cell.
Sickle cell disease is one of many diseases of the red blood cell.
There is only one normal type of red blood cell.
The heme "assembly line" is an eight-step process, requiring eight different and properly functioning enzymes.
This is a complicated question, iron is used in our body for many chemical interactions that are needed for cellular and bodily function! However, in general, iron aids enzymes in carrying out many interactions that involve the transport or recruitment of oxygen. Most notably, iron participates in what are called "heme" groups. These groups are essential for the protein hemoglobin to perform its duty. Hemoglobin is used in red blood cells, which transport and deliver oxygen throughout the body in the bloodstream. Heme groups are also very important in the electron transport chain, our main source of ATP. Think of ATP as the cell's gasoline, it is used to fuel reactions in the cell and keep it functioning. So, iron is SUPER important in our everyday life and is used in some of the most important chemical reactions in our body.
