But it has been found that a mitochondrial outer-membrane protein, VDAC2, interacts with BAK ... VDAC2: BAK and BAX are activated, and the mitochondrial outer-membrane becomes permeable, aparently these ...

ATP synthase

Electron transfer chain

... humans, an ETC is found spanning the inner mitochondrial membrane and accepts electrons from electron ... , shuttles these electrons from within the mitochondrial matrix across the inner mitochondrial membrane into the intermembrane space, where the ...

Human

Enzymes destined for the mitochondrial matrix or the stroma can bypass the intermembrane space via transport ... of the proton gradient which results when protons are pumped from the mitochondrial matrix into the intermembrane space during electron transport . The ...

Oxidative phosphorylation

... is the plasma membrane , and in eukaryotes it is the inner of the two mitochondrial membranes . NADH and FADH 2 , electron carrier molecules that were ... intermembrane space against the gradient, they now can flow back into the mitochondrial matrix via the ATP synthase, generating ATP in the process. The reaction ...

Chemiosmotic hypothesis

... functioned as a kind of electrochemical capacitor , using the energy of NADH and FADH 2 to create a proton gradient across the mitochondrial membrane and that this energy was used by a reversible proton pump , the ATP synthase , to create ATP . This was a radical proposal at the ...

Cloning

... all of the genetic information of a lifeform, the "host" egg cell will develop into an organism genetically identical to the nucleus "donor". mitochondrial DNA , which is not transferred by this process, is generally ignored as its effects on organisms are thought to be relatively minor. The term ...
