mitochondrial intermembrane/intercristae spacesIn healthy cells, cytochrome c (Cyt c) is located in the mitochondrial intermembrane/intercristae spaces, where it functions as an electron shuttle in the respiratory chain and interacts with cardiolipin (CL).
mitochondriaThey are present in bacteria, chloroplasts, and mitochondria. The mitochondrial b-type cytochromes are normally embedded in membranes as part of complex II of the electron transport system.
Terms in this set (33) Cytochrome c, an essential protein of the electron transport chain, is located in the mitochondria.
This complicated facilitates switching the electron to oxygen. - Thus, cytochromes are present in the electron transport chain, which are required for electron transfer. Thus the precise solution is option (D) 4.
Solution : Cytochrome c is attached to inner surface of inner membrane of mitochondria. It functions as mobile carrier for transfer of electrons between complex III and complex IV.
A cytochrome is an enzyme that catalyzes redox reactions and is usually in the oxidoreductase enzyme class.
Cytochrome c is functionally involved in the electron transport chain of mitochondria. That electron transport is part of the pathway for synthesis of ATP. The role of cytochrome c is to carry electrons from one complex of integral membrane proteins of the inner mitochondrial membrane to another (Fig. 10.3).
Mitochondrial electron transfer is carried out by the protein complexes that make up the electron transport chain, which are located in the mitochondrial inner membrane.
Cytochrome c is a water soluble electron transport protein that is loosely associated with the mitochondrial inner membrane. It contains a heme iron metal center that is essential to it's function in the ETC.
Cytochrome c is an important component of the Electron Transport Chain for the synthesis of ATP (Figure 2). Cytochrome c is a water soluble electron transport protein that is loosely associated with the mitochondrial inner membrane.
During aerobic respiration, or cellular metabolism in the presence of oxygen, ATP synthesis is facilitated by the electron transport chain. ATP represents the energy currency in cells, and the electron transport chain constitutes the final step in ATP synthesis.
The International Union of Biochemistry currently recognizes four different groups of cytochromes:
The basic structure of a cytochrome complex consists of a porphyrin ring with an embedded heme prosthetic group. Porphyrins are made of four pyrrole rings comprised of four carbons and a nitrogen. The iron center of the heme group is responsible for electron transport as it shifts between its ferrous (Fe2+) and ferric (Fe3+) forms.
