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.
Eggs should be thoroughly cooked until both the yolk and white are firm. Recipes containing eggs mixed with other foods should be cooked to an internal temperature of 160Â°F (71Â°C). Eat eggs promptly after cooking. Do not keep eggs warm or at room temperature for more than 2 hours. Refrigerate unused or leftover egg-containing foods promptly.
