How many oxygen molecules bind to myoglobin? - Answers

WebEach iron ion in the heme can bind to one oxygen molecule therefore each hemoglobin molecule can transport four oxygen molecules. An individual erythrocyte may contain about 300 million hemoglobin molecules and therefore can bind to and transport up to 1.2 billion oxygen molecules (see (Figure)b). WebUsually, Oxygen is consumed in the lungs by haemoglobin and passed all through the body’s circulatory system. A molecule of haemoglobin has 4 sites to bind for oxygen molecules – the iron atoms in the 4 heme groups. Consequently, each of the Hb tetramer can bind 4 oxygen molecules.

The shape of the O 2 -binding curve of myoglobin can be described …

WebYeah got the right idea, but this doesn't mean that CO2 doesn't decrease O2's affinity for hemoglobin. Like you said, CO2 can bind to the hemoglobin subunit causing a conformational change of the protein decreasing O2 affinity for the molecule; this is known as allosteric inhibition.ALSO CO2 can react with H2O eventually leading to the creation … WebFigure 2.
