The processes that use the mechanisms are: Cellular respiration â ATP is generated by oxidation of organic molecules, the passage of electrons down an electron transport chain, and chemiosmosis. The final electron acceptor is almost always inorganic. Aerobic â the final electron acceptor is O 2.
The Sumerians lived in Mesopotamia around 4000 BC. Mesopotamia or the Fertile Crescent was a region in the Middle East between the Tigris and Euphrates rivers, in the territory of modern Iraq, Iran and Syria.
Practice makes perfect. After centuries of trying to become masters of their world, the Assyrians succeeded -- with a vengeance. A Semitic people, the Assyrians lived in the northern area of Mesopotamia, the land between the Tigris and Euphrates Rivers at the city-state of Ashur.
