What is Intracristal space?
Gene Ontology Term: mitochondrial intracristal space The space bounded by the mitochondrial cristae membranes, continuous with the intermembrane space.
What is mitochondrial space?
In cell biology, it is most commonly described as the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast. It also refers to the space between the inner and outer nuclear membranes of the nuclear envelope, but is often called the perinuclear space.
What is the function of intermembrane space?
The intermembrane space is a compartment of very small volume since the outer and inner membranes are in very close proximity. Only a relatively small number of components of the intermembrane space are known, most of which are required for mitochondrial biogenesis or have a function in energy metabolism.
What is the space between the cristae in mitochondria?
As those electrons travel farther through the electron transport chain in the inner membrane, energy is gradually released and used to pump the hydrogen ions from the splitting of NADH and FADH2 into the space between the inner membrane and the outer membrane (called the intermembrane space), creating an …
What is the function of mitochondrial cristae?
The folds, called cristae, provide a scaffold for the molecular machinery that produces chemical energy that the cell can use. The cristae are dynamic, and can change shape, condensing to increase energy output. Mitochondria also play a role in cell death.
What is the purpose of the mitochondrial matrix?
The Mitochondrial Matrix Defined It is where the citric acid cycle takes place. This is an important step in cellular respiration, which produces energy molecules called ATP. It contains the mitochondrial DNA in a structure called a nucleoid.
Where are mitochondria located?
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).
What takes place in the intermembrane space?
the intermembrane space: holds protons that are pumped out of the matrix during electron transport, the inner mitochondrial membrane: organizes the electron transport chain and holds ATP synthase, the matrix: site of ATP synthesis and the location of the Krebs cycle.
What is the function of Perimitochondrial space?
Intermembrane space It is also known as perimitochondrial space. Because the outer membrane is freely permeable to small molecules, the concentrations of small molecules, such as ions and sugars, in the intermembrane space is the same as in the cytosol.
What is the function of the intermembrane space in mitochondria?
The intermembrane space, as implied, is the region between the inner and outer membranes. It has an important role in the primary function of mitochondria, which is oxidative phosphorylation. The matrix contains the enzymes that are responsible for the citric acid cycle reactions.
