mitochondira cell appendages by diego Valencia and Alejandro Dada Juan Pablo Mitochondria Mitochondria are membrane-bound cell organelles mitochondrion, singular that generate most of the chemical energy needed to power the cell's biochemical reactions. cell appendages The three types of cell surface appendages of bacteria are flagella, pili, and fimbriae. The overall functions of these appendages are to provide motility and attachment to the bacterial cell. The bacterial flagellum is a whip-like structure that assists in a cell's motility. The initial stages of glucose metabolism glycolysis occur in the The Krebs CycleThe second stage of cellular respiration is the transfer cytosol, where glucose is converted to pyruvate see Figure of the energy in pyruvate, which is the energy initially in glucose, into 2.32. Pyruvate is then transported into mitochondria, where two energy carriers, NADH and FADH2. A small amount of ATP is also its complete oxidation to CO2 yields the bulk of usable energy made during this process. This process occurs in a continuous cycle, ATP obtained from glucose metabolism. named after its discover, Hans Krebs. The third and final stage of cellular respiration, called electron transport , takes place on the inner membrane of the mitochondrion. Electrons are transported from molecule to molecule down an electron-transport chain
