Carbohydrates are primarily metabolized for energy, with glucose being the most significant source. The process begins with glycolysis<\/strong>, where glucose is broken down into pyruvate, yielding ATP, the cell’s energy currency. From there, pyruvate is converted into acetyl-CoA<\/strong>, entering the citric acid cycle<\/strong> (Krebs cycle), where it undergoes oxidation to produce more ATP, NADH, and FADH2. These molecules then feed into the electron transport chain<\/strong>, where ATP is generated.<\/p>\n\n\n\n
Fats, primarily in the form of triglycerides, undergo lipolysis<\/strong>, breaking down into fatty acids and glycerol. Fatty acids then enter the mitochondria where they are broken down through beta-oxidation<\/strong> into acetyl-CoA<\/strong>, which again enters the citric acid cycle for further energy production. The key enzymes in this pathway include lipase<\/strong> and acyl-CoA synthetase<\/strong>. Fatty acid metabolism is especially important during fasting or prolonged exercise when the body relies on fat stores for energy.<\/p>\n\n\n\n
Proteins are broken down into amino acids by the process of proteolysis<\/strong>. Amino acids are then deaminated, and their carbon skeletons can be converted into acetyl-CoA<\/strong>, pyruvate, or other intermediates that enter the citric acid cycle. Some amino acids can also directly contribute to gluconeogenesis (the production of glucose from non-carbohydrate sources). The metabolism of amino acids is highly regulated to prevent excess buildup, as ammonia, a byproduct of deamination, is toxic.<\/p>\n\n\n\n
