Oxidative phosphorylation

... Because protons have already been pumped into the 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 is: ADP 3- + H + + P i ↔ ATP 4- + H 2 O Each NADH molecule contributes enough proton m...

Intermembrane space

The intermembrane space is the region between the inner membrane a... movement of ions and small molecules into the intermembrane space. This means that it is essentially continuous with the cytosol in terms of solutes releven...

Electron transfer chain

... across the inner mitochondrial membrane into the intermembrane space, where the ultimately reduce oxygen . There are five complexes normally associated with the mitochondrial electron transfer chain . Complex I - NADH dehydrogenase , also called NADH coenzyme Q reductase. Complex II - Succinate - coenz...

Chloroplast membrane

... two are separated by a gap of 10-20nm, called the intermembrane space. The outer membrane is permiable to most ions and metabolites , but the inner membrane is highly specialised with transport proteins . Within the inner membrane, in the region called the stroma , there is a system of interconecting flatte...

Chloroplast

...nelles are surrounded by a double membrane with an intermembrane space; both have their own DNA and are involved in energy metabolism; and both have reticulations, or many foldings, filling their inner spaces. Chloroplasts convert light energy from the sun into ATP through a process called photosynthesis . Chl...
