During oxidative phosphorylation, electrons are transferred from electron donors to electron acceptors such as oxygen, in redox reactions. These redox reactions release energy, which is used to form ATP.In eukaryotes, these redox reactions are carried out by a series of protein complexes within the inner membrane of the cell's mitochondria, whereas, in prokaryotes, these proteins are located in the cells' intermembrane space.or another twenty years, the mechanism by which ATP is generated remained mysterious, with scientists searching for an elusive high-energy intermediate that would link oxidation and phosphorylation reactions. This puzzle was solved by Peter D. Mitchell with the publication of the chemiosmotic theory in 1961.
Giant Pacific Octopus. GIANT PACIFIC OCTOPUS (Enteroctopus dofleini) is the largest species of octopus in the world. It is found in the northern Pacific Ocean from the northwest coast of the continental United States to Japan, including Puget Sound. When fully extended from arm tip to arm tip, the Giant Pacific Octopus can measure an average of 16 feet long.
Octopus Octopus are mollusks like squid. There are about 200 species of octopus. There are two large groups of octopus. The cirrata or finned octopuses live in the deep sea at depths of between 1000 and 24,000 feet. About 85% of octopus are in the incirrata group. They have no fins and live in shallow water in caves or crevices. Octopus have no shell at all, not even an inner one. They have eight tentacles. The tentacles have suction cups on them and are used to hold onto prey. The tentacles also have taste sensors that let the octopus know if what it grabbed is worth eating. The octopus' mouth is in the center of its tentacles.
