Hemoglobin also meets the modulation effects and gas transport as a different task, although it will differ from species to species and is likely to be completely different in invertebrates. Some oxygen is dissolved in the blood while some are bound to hemoglobin. However, the more oxygen molecules are carried with hemoglobin, the more oxygen in reaching every part of the body. Therefore this pack of chemicals known as hemoglobin performs the most important task to bind the oxygen so as to reach each and every part of the body.
@manah It is certainly very important and complementary, but my fascination with chlorophyll comes from its role in the synthesis of simple sugars, from which other processes of primary metabolism happen. Thanks for stopping by here! 😊
