What Mechanical Engineers Do. Mechanical engineers develop and build mechanical devices for use in industrial processes. Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical and thermal sensors and devices, including tools, engines, and machines.
Each tissue is with metabolic enzymes to release energy. Red blood cells do not have mitochondria . They get energy through glycolysis. Tissues like muscles have mitochondria . When muscles need energy mitochondria through mitochondria release more energy. Liver is the primary organ of metabolism. In liver carbohydrates, lipids and amino acids are metabolized. All tissues other than liver can metabolism carbohydrates fat and amino acids.
The most critical aspects of protein metabolism that occur in the liver are: Deamination and transamination of amino acids, followed by conversion of the non-nitrogenous part of those molecules to glucose or lipids.
