What are mitochondrial membrane markers?
Mitochondrial markers are structural or functional properties that are specific for mitochondria. A structural mt-marker is the area of the inner mt-membrane or mt-volume determined stereologically, which has its limitations due to different states of swelling.
Which is the marker of the inner membrane?
The percoll-purified mitochondrial fractions demonstrate an enrichment of VDAC (outer membrane marker) and COX (inner membrane marker) protein levels compared to the brain homogenate and the crude mitochondrial fractions.
What is a good marker for mitochondria?
Cytochrome C, COX IV and HSP60 are markers for mitochondrial organelle.
What is the structure of mitochondrial membrane?
As previously mentioned, mitochondria contain two major membranes. The outer mitochondrial membrane fully surrounds the inner membrane, with a small intermembrane space in between. The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein.
What is mitochondrial marker enzyme?
Description. Mitochondrial marker enzymes are enzymes that are specifically present in mitochondria, in the mt-matrix, the inner mt-membrane, the inter-membrane space, or the outer mt-membrane.
What can be used as a functional marker for mitochondria?
I believe that succinate dehydrogenase and cytochrome C genes would be most ideal markers for mitochondrial function. For direct mitochondrial function, expression of subunits of the electron transport chain complexes (take care if you measure mt coded or nucleus coded subunits) or citrate synthase.
What are the mitochondrial marker enzymes?
Mitochondrial marker enzymes are enzymes that are specifically present in mitochondria, in the mt-matrix, the inner mt-membrane, the inter-membrane space, or the outer mt-membrane.
What is the marker enzyme for plasma membrane?
Potentially, adenyl cyclase is the best plasma membrane marker enzyme.
Why is SDH a good mitochondrial marker?
Succinate dehydrogenase is a mitochondrial marker enzyme. It is one of the hub linking oxidative phosphorylation and electron transport. It can provide a variety of electron in respiratory chain for eukaryotic and prokaryotic cell mitochondria.
How is the structure of the mitochondria related to its function?
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.
What is the function and structure of mitochondria?
A mitochondrion is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms. It produces energy, known as ATP, for the cell through a series of chemical reactions.
What are marker enzymes?
Marker enzymes are enzymes, which are not ubiquitous but confined to a specific type of organelle, a subcomponent, or a cell. Marker enzymes are one of the cell biomarkers used to characterize a cell type. They are also used in the isolation of the target cellular component.
