of potential energy being accumulated within the gradient creating ATP from phosphate and ADP. The inner mitochondrial membrane house the electron transport chain, which is organized in a sequential
formation. The vast majority of electron carriers are "tightly associated with proteins embedded in the membrane" (Multimedia Development Lab, 1997), which creates three distant complexes that are solidly kept
within the membrane. Chemiosmotic coupling represents the ATP synthesis mechanism; that production of ATP in oxidative phosphorylation is comprised of a combination of transport and chemical processes that
traverse a "selectively permeable membrane" (Multimedia Development Lab, 1997) characterizes the term chemiosmotic. As such, chemiosmotic coupling creates two different occurrences: 1. a proton gradient is established
across the inner membrane of the mitochondrion 2. potential energy stored in the gradient is used to generate ATP from ADP and phosphate (Multimedia Development Lab, 1997).
Its association with the mitochondrion is such that stored proton gradient energy has a secondary task of moving other matter through the inner membrane.
Moreover, pyruvic acid and phosphate are transported into the environment by the same membrane proteins that also move gradient protons (Multimedia Development Lab, 1997). What makes the mitochondria
the primary energy source of the cell is the cytochrome enzymes of terminal electron transport, along with the critical enzymes of the citric acid cycle, fatty acid oxidation, and oxidative
phosphorylation. This process helps the mitochondria transform nutrients into much needed energy while also accomplishing a number of other specific tasks. There is no difference in origin of
mitochondrial chromosome when addressing that of a male or female for the reason that the mother is the sole source of such genetic inheritance. Mitochondria are sometimes referred to as
