WebOur results is agreement with the ‘reverse Warburg effect’ model, that glycolysis in non-malignant stromal cells result in production of energy-rich metabolites such as lactate and pyruvate, which can be taken up by cancer cells as an alternative TCA cycle substrate, facilitating energy production and tumour growth. 64 65 Besides enhancing ... WebGlycolysis literally means the breakdown of sugar (Glyc = sugar or sweet and Lysis = to cut or loosen). Glycolysis occurs in the cytoplasm of the cell. ... then a dehydrogenase enzyme will perform a reaction that is actually the reverse of what we saw in step 4. A hydrogen ion and 2 electrons will be removed from NADH and put onto pyruvate.
