The process, in which an eukaryotic cell divides, is either meiosis or mitosis. Gametes or sex cells divided by meiosis. While Somatic cells or body cells, divide my mitosis.
These reactions produce ethanol in yeast, and lactic acid in mammalian cells (muscle cells under oxygen deficit). Fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells. Energy metabolism in eukaryotes vs prokaryotes. In prokaryotic cells, all the metabolic pathways occur in the cytoplasm, except for chemiosmosis and oxidative phosphorylation, which occur on the plasma membrane.
