Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: A cikin anabolism na carbohydrate, za a iya canza acid mai sauƙi zuwa monosaccharides kamar glucose sannan a yi amfani da shi don tara polysaccharides kamar sitaci. Halitta glucose daga mahaɗan kamar pyruvate, lactate, glycerol, glycerate 3-phosphate da amino acid ana kiranta gluconeogenesis. Gluconeogenesis yana canza pyruvate zuwa glucose-6-phosphate ta hanyar jerin tsaka-tsakin, da yawa daga cikinsu ana raba su tare da glycolysis. Koyaya, wannan hanyar ba kawai glycolysis ba ne wanda aka juya baya, kamar yadda matakai da yawa ke haifar da enzymes marasa glycolytic.
