The key difference between glyoxysomes and peroxisomes is thatglyoxysomes are present only in plant cells and filamentous fungi while peroxisomes are present in almost all真核细胞.Glyoxysomes are abundant in plant cells of germinating seeds while peroxisomes are abundant in liver and kidney cells.
这两个细胞器是真核细胞中存在的微生物。乙氧基体是仅在植物细胞和丝状真菌中发现的专门过氧化物酶体。过氧化物酶体是有助于分解长时间的细胞器fatty acidchains and detoxify the cell. They degrade alcohols and other harmful compounds.
What are Glyoxysomes?
Glyoxysomes are a specialized form of peroxysomes present in plant cells, notably in the cells of germinating seeds. They are also present in filamentous fungi. Harry Beevers discovered this organelle in 1961.
糖明的主要功能是形成的催化acetyl CoAfrom fatty acids stored within germinating seeds. Hence, some key enzymes of glyoxylate cycle are present in this organelle. They are isocitrate lyase and malate synthase. Furthermore, they contain some enzymes of gluconeogenesis pathway as well. This organelle also helps in photorespiration and nitrogen metabolism in root nodules.
Peroxysomes are sub-cellular organelles present in most eukaryotic organisms including fungi, protozoa, plants, and animals. Christian de Duve identified this organelle in 1967. They help in the breakdown of toxic compounds (Ex: H2O2) of the cells that can cause damages. In addition, they degrade alcohols and fatty acids as well. For this purpose, this organelle contains enzymes such as oxidases, peroxidase, catalase, etc.
Moreover, peroxisomes also have a role in the formation of phospholipids that are essential for the development of myelin sheaths around the axons.
What are the Similarities Between Glyoxysomes and Peroxisomes?
- Glyoxysomes and peroxisomes are subcellular organelles.
- They are capable of respiration.
- Both organelles contain enzymes of glyoxylate pathway.
- They are present in major groups of eukaryotic organisms.
- They are spherical or oval in shape.
- Both these organelles are microbodies.
|Glyoxysomesare specialized peroxysomes that are present in plants and filamentous fungi.
