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 Using a thermometer to measure the internal temperature of meat can be used to ensure that it is cooked sufficiently to kill bacteria. 2  Ground beef should be cooked to an internal temperature of 160Â°F. Eggs should be cooked until the yolk is firm. 2  Use Proper Cooking Temperatures to Ensure Safe Food. 3  This printable chart gives cooking temperatures. 4  The key to safe cooking is the proper internal temperature to kill the organisms that might make you sick. 5  Use a thermometer to check temperature.
