Mitochondria and Respiration

A very readable site with many illustrations. This site provides a concise explanation of the process of cell respiration and the structure of the mitochondrion.

The Krebs Cycle or Tricarboxylic acid cycle

The official Nobel citation for Dr Hans Krebs (discoverer of the Kreb's cycle) and Dr Fritz Lipmann (who discovered the role of Coenzyme A or CoA) for the 1953 Nobel Prize in Medicine. This citation briefly describes their discoveries and their significance.

The Electron Transport Chain and Chemiosmosis

The press release that accompanied the announcement that Dr Peter Mitchell had been awarded the Nobel Prize for Chemistry in 1978. This release briefly outlines the process that Mitchell called "chemiosmosis". This concept of chemiosmosis describes the indirect link between the cascade of electrons through the electron transport chains of chloroplasts and mitochondria and the synthesis of ATP by a hydrogen ion gradient (which Mitchell called the proton motive force).

Oxidative Phosphorylation and the Function of ATP synthase

The press release that accompanied the announcement that Drs Peter Boyer and John Walker had been awarded the 1997 Nobel Prize for Chemistry for discovering how ATP synthase (ATPase) converts the energy of a hydrogen ion gradient into ATP. Boyer proposed a model which was confirmed by the research of Walker andhis associates. The release also details the work of Dr Jens Skou, who shared the 1997 prize with Boyer and Walker. Skou discovered the Na⁺, K⁺ -ATPase (or sodium-potassium pump) in ground crab nerve membranes, the first such ion pump.
