Chloroplast

... . Chloroplasts are similar to mitochondria but are found only in plants. Both organelles 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. ...

Chloroplast membrane

... envelope . Each membrane is a phospholipid bilayer , between 6 and 8 nm thick, and the 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 . ...

Electron transfer chain

... such as NADH or succinate , shuttles these electrons from within the mitochondrial matrix 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 . ...

Oxidative phosphorylation

... proton moves with (down) the gradient, and it costs ATP to pump a proton against (up) the gradient. 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 ...
