Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.herefore, power-hungry cells have more mitochondria than cells with lower energy needs. For example, repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell, to keep up with energy demand.
To prevent food-borne illness, U.S. Department of Agriculture (USDA) recommends cooking eggs until the whites are firm and yolks are thickened. Cook egg-containing dishes to an internal temperature of 160Â°F (71Â°C). For egg preparations not cooked to these guidelines, pasteurized shell eggs are available on the market.
Note: The temperature of the egg at the start of the cooking process will affect the cooking time. An egg that is at room temperature at the start of the cooking process will require about 1 minute less cooking time for each time listed above. The times listed above are based on eggs taken directly from the refrigerator. After the required time has elapsed, run cold water over the eggs to stop the cooking process.
