How well do you know about extracellular digestion? Extracellular digestion is a biological process where food is broken down outside the cell either mechanically or with acid by special molecules called enzymes, then the newly broken down nutrients can be absorbed by the cells nearby. This occurs in specialized structures or compartments, such as the digestive system. This breakdown enhances nutrient absorption by individual cells, supporting the energy needs of multicellular organisms. It is a pivotal mechanism in diverse organisms, from fungi releasing enzymes into their surroundings to absorb nutrients to animals employing digestive systems for efficient external digestion before internal absorption of essential compounds, and Humans use extracellular digestion when they eat.
