They reduce and oxidize in the electron transport chain
Heme + globin is Hemoglobin.
in the thylakoid membrane of chloroplasts within the plant cell. These complexes capture light energy and transfer it to chlorophyll molecules, which then initiate the process of photosynthesis by converting light energy into chemical energy in the form of ATP and NADPH.
Heme is decomposed into iron and biliverdin
The breakdown product of heme is bilirubin. Bilirubin is produced when heme is broken down in the liver as a part of the normal process of recycling heme from old red blood cells.
Heme iron comes from animal sources, while non-heme iron comes from plant sources, so I believe that because mussels are animals, mussels therefore do contain heme iron. Fish also contains heme iron.
When heme levels are low, more delta-aminolevulinic acid (ALA) synthase are produced. Causing larger quantities of heme precursors to be fed into the biosynthesis path producing more heme.
Heme synthesis occurs in the liver and bone marrow and involves a series of enzymatic reactions that convert succinyl-CoA and glycine to heme. Heme is a component of hemoglobin, necessary for red blood cell function and oxygen transport in the body. Deficiencies in heme synthesis can lead to diseases such as porphyrias.
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
The Heme protein database refers to the protein sequence databases.
Photosynthesis takes place in the Chloroplasts of the plant cell because it contains chlorophyll, the proteins required for photosynthesis, and the membranes needed to make a chemiosmotic gradient to produce ATP.in the chloroplasts of plant cells (not animal cells)
Heme iron is more efficiently absorbed by the body, but non-heme iron can also be effective if used in conjunction with vitamin C and other dietary sources of heme iron.
No, spinach is not a source of heme iron. Heme iron is primarily found in animal products, particularly in red meats and seafood. Spinach contains non-heme iron, which is found in plant-based foods. While non-heme iron is less easily absorbed by the body than heme iron, consuming vitamin C-rich foods alongside spinach can enhance its absorption.
