What is intracellular digestion?
Intracellular digestion, or cellular digestion, is the breaking in the interior of the cell of big molecules coming from outside or even from its own cell metabolism into smaller molecules. Products and residues of the intracellular digestion are used by the cell or excreted. Intracellular digestion is classified into two types: heterophagic intracellular digestion and autophagic intracellular digestion.
