In this stage numerous reactions can occur in the cell’s cytoplasm, and glycolysis will then take the molecule and break it down. The stage of cellular respiration is Krebs cycle, this cycle happens in mitochondria in eukaryotes and also in cytoplasm in prokaryotes. There are many steps to this cycle however enzymes, and catalysts have a big role in individual reactions. The pyruvic acid in created by reactions in glycolysis go through multiple reactions and create carbon dioxide and other products. The next stage in aerobic respirations is electron transport chain. In this stage multiple reactions create energy for cells. Oxygen is important to this stage because it serves as acceptor at the end of the chain. And then oxygen combines with hydrogen and creates water, this process looks like C6H12O6+6O2-
