The inner membrane of mitochondria contains an electron transport chain and an ATP synthase. This is because oxidative phosphorylation, the third and final step in cellular respiration, occurs in the mitochondrial inner membrane. The electron transport chain is comprised of protein complexes of electron carriers (I, II, Q, III, Cyt c, and IV), and the ATP synthase is made up of a rotor, stator, rod, and a knob with 3 catalytic sites.
In case you'd also like to know how the electron transport chain and ATP synthase works:
NADH and FADH2 shuttle high-energy electrons extracted from food during glycolysis and the citric acid cycle to the electron transport chain. As the electrons are transported "downhill" from protein complex to protein complex with increasing electronegativity, H+ is pumped into the mitochondrial intermembrane space and flows down its gradient back across the membrane through the ATP synthesis, producing ATP through chemiosmosis.

Which are the two parts of mitocharda?
The two main parts of a mitochondrion are the outer membrane and the inner membrane. The inner membrane is where the electron transport chain and ATP synthesis occur, while the outer membrane helps separate the contents of the mitochondrion from the rest of the cell.
What are the projections on the inner membrane of a mitochondria called?
The convolutions in the inner membrane of a mitochondrion are referred to as the cristae. Mitochondrion refers to an organelle found in most cells whereby energy production and respiration takes place.
What organelle contains a smooth outer and folded inner membrane in a cell?
The chloroplast of plant cells and the mitochondrion of animal cells. Both of these are involved in the production of energy and are derived from the secondary endosymbiosis of an alga (in the case of the chloroplast) or a cyanobacteria (in the case of the mitochondrion).
Is the mitochondrion surrounded by a membrane?
Mitochondria have two [bi-lipid layer] membranes: a smooth and slightly elastic outer membrane and an inner membrane that has [surface area increasing] inward folds called cristae. Inside the inner compartment is the 'matrix', which is a gel-like phase that contains about 50% protein.
What are the folded inner membranes inside mitochondria are called?
The folded inner membranes inside mitochondria are called cristae. These structures increase the surface area available for chemical reactions that produce adenosine triphosphate (ATP), the cell's main energy source.
What is Mitochondrial Matrix?
The Fluid that is inside the inner membrane of a mitochondrion.
What are the folded inner membranes inside mitochondria?
The inner membrane folds in a mitochondrion are called cristae.
What are the parts of a mitochondrion?
A mitochondrion consists of an outer membrane, an inner membrane, cristae (folds in the inner membrane), a matrix (fluid-filled space inside the inner membrane), and ribosomes and DNA for protein synthesis within the matrix.
What is the large central fluid filled cavity of a mitochondrion enclosed by the inner mitochondrial membrane?
Matrix
Structure of a mitochondria?
A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The two membranes, however, have different properties. Because of this double-membraned organization, there are five distinct compartments within the mitochondrion. There is the outer mitochondrial membrane, the intermembrane space (the space between the outer and inner membranes), the inner mitochondrial membrane, the cristae space (formed by infoldings of the inner membrane), and the matrix (space within the inner membrane).
A single mitochondrion consists of?
An outer membrane and an inner membrane, the inner membrane being used during cellular respiration
What steps of celuar respiration occurs inside the mitochondrion?
Kreb cycle in cristae.The electron transport chain in inner membrane.
WHere within the cells does cellular desperation occur?
It begins in the cytoplasm and then moves into the mitochondrion if there is enough oxygen present. Inside the mitochondrion it occurs in the matrix (center area) and the inner membrane.
Which are the two parts of mitocharda?
The two main parts of a mitochondrion are the outer membrane and the inner membrane. The inner membrane is where the electron transport chain and ATP synthesis occur, while the outer membrane helps separate the contents of the mitochondrion from the rest of the cell.
What are the projections on the inner membrane of a mitochondria called?
The convolutions in the inner membrane of a mitochondrion are referred to as the cristae. Mitochondrion refers to an organelle found in most cells whereby energy production and respiration takes place.
What is Mitochondria (mitochondrion)?
Mitochondria (singular: mitochondrion) have two membranes, with an intermembrane space between them. The inner membrane is folded to form cristae. The space inside the mitochondria is known as the matrix and is where the reactions happen to make ATP.
What is the structure of a mitochondrion?
The mitochondria is the powerhouse of the cell. It has two membranes. The outer membrane covers the organelle and contains it. The inner membrane folds over many times. This folding increases the surface are inside the organelle.
