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.
1 Use a food thermometer to measure the internal temperature of cooked foods. 2  Check the internal temperature in several places to make sure that the meat, poultry, seafood, eggs or dishes containing eggs are cooked to safe minimum internal temperatures as shown in the Safe Cooking Temperatures Chart. Refrigerate or freeze meat, poultry, eggs, seafood and other perishables within 2 hours of cooking or purchasing. 2  Refrigerate within 1 hour if the temperature outside is above 90ÂºF. 3  Never thaw food at room temperature, such as on the counter top.
