Does intracellular or extracellular digestion occur in the stomach? Why?
Intracellular nor extracellular digestion occur in the human stomach. Intracellular digestion is digestion taking place inside of cells. However, most intracellular digestion takes place in uni-cellular protists which do not have a stomach. Instead, the cell engulfs the food particle by phagocytosis. The food particle enters through a coated vesicle and eventually attaches to a lysosome, which contains digestive enzymes which break down the food. Extracellular digestion is digestion that occurs OUTSIDE of cells. More complex organisms (i.e. humans) have extracellular digestion. I do not think you want an explanation of how this happens, plus my arms are very tired. So, to conclude and attempt to answer your question, intracellular nor extracellular digestion occur in the human stomach. I am not 100% sure if humans can go through intracellular and extracellular digestion. I don’t think they can. I do know a hydra can.
