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.
Cooking Raw meat and poultry should always be cooked to a safe minimum internal temperature. When roasting meat and poultry, use an oven temperature no lower than 325 Â°F. Use a food thermometer to assure that meat and poultry have reached a safe minimum internal temperature. Cook all raw beef, pork, lamb and veal steaks, chops, and roasts to a minimum internal temperature of 145 Â°F as measured with a food thermometer before removing meat from the heat source. For safety and quality, allow meat to rest for at least three minutes before carving or consuming.
