Mitochondrial membrane

Biology Mitochondrial DNAMitochondrion

The outer mitochondrial membrane, which encloses the entire organelle, has a protein-to-phospholipid ratio similar to that of the eukaryotic plasma membrane (about 1:1 by weight). It contains numerous integral proteins called porins.

 


In eukaryotes, including humans, an ETC is found spanning the inner mitochondrial membrane and accepts electrons from electron donors such as NADH or succinate, ...

Most of the ATP is generated by the proton gradient that develops across the inner mitochondrial membrane.

cristae - folds of the inner mitochondrial membrane
DNA helicase - an enzyme that participates in DNA replication by unwinding the double helix near the replication fork
DNA ligase - fills in nicks and gaps made in polynucleotide strands ...

H+ ions pass back from space between two mitochondrial membranes into matrix
Through pores which are associated with the enzyme ATP synthetase
Energy from the ETC will be used to produce ATP

A class of protein, found in mitochondrial membranes, whose main function is oxidative phosphorylation of ADP to form ATP.

ATP synthase Molecular assembly of the inner mitochondrial membrane responsible for the respiratory-chain-driven synthesis of ATP. Also called Complex V, mitochondrial atpase, H+-atpase, or F0F1-atpase.

This image depicts one of the many OXPHOS systems embedded in the inner mitochondrial membrane. These are the sites of ATP generation and the utilization of oxygen as the ultimate electron acceptor.

The mechanism for the oxidative phosphorylation process is the gradient of H+ ions discovered across the inner mitochondrial membrane. This mechanism is known as chemiosmotic coupling. This involves both chemical and transport processes.

the Proton Motile Force, which at last of all is the main characteristic of the quantum energy state of life, be by synthesizing viral proteins, or by destroying the liposome's membranes, the chloroplasts' membranes, the mitochondrial membranes, ...

The matrix is the area of the mitochondrion surrounded by the inner mitochondrial membrane. Ribosomes and mitochondrial DNA are found in the matrix. The significance of these features will be discussed below.
