Mitochondria generate the energy that a cell needs to function properly. They are often described as the powerhouse of the cell. They are also involved in signaling, cellular differentiation, cell death, maintenance of cell growth and control of the cell cycle.Continue Reading
Mitochondria create chemical energy in the form of a chemical called adenosine triphosphate through a machinery known as the electron transport chain. The chain is created by four complexes created of groups of proteins and a fifth complex that is responsible for the final step of energy generation.
In order for the process to occur, electrons must be passed between the complexes of the chain. The first complex accepts the electrons. Electrons are then moved to the third complex while protons cross the inner mitochondrial wall. In the third complex the electrons are joined with others donated from the second complex. Complex three then passes the electrons to complex four as more protons move across the inner mitochondrial membrane.
In the fourth complex, electrons are joined to oxygen which creates water, and protons cross the membrane once again. A gradient is created as a result of the movement of so many protons. This gradient is used to rotate the fifth complex, creating an adenosine triphosphate with every rotation.Learn more about Cells
Mitochondria give off water, carbon dioxide and energy, in the form of ATP molecules, during cellular respiration. Mitochondria produce these by combining glucose and oxygen molecules, which creates the molecules and releases large amounts of energy. This is the main process by which most organisms meet their energy needs.Full Answer >
Mitochondria generate energy for cells from food items the cells take in or create. They convert the chemical energy from compounds into a form accessible by the cells. This energy is ATP, a specific molecule that all cells use to store and transport energy.Full Answer >
Liver cells have been found to have the most mitochondria with an estimated 1,000 to 2,000. Mitochondria can be found in all living cells.Full Answer >
Aerobic respiration on the cellular level occurs in the cell's mitochondria, according Georgia State University. Respiration transforms pyruvate into adensoine triphosphate through the TCA cycle in mitochondria. The TCA cycle, also known as the Krebs cycle, uses enzymes to transport electrons among water, oxygen, carbon and other atoms.Full Answer >
