digestion+of+cells+and+organisms

====The Primary cites of intracelular digestion are organelles known as the lysosomes, which are membrane-bounded compartments containing a variety of hydrolytic enzymes. Lysosomes maintain an internal acidic enviroment through the use of a hydrogen ion pump in the lysosomal membrane that drives ions from the cytoplasm into the lumenal space or the organelles. The high interia acidity is necrssary for the enzymes contained in lysosomes to exibit their own otimum activity. Hence if the integity of a lysosomal membrane is compromised and the enzyin matic contents are leaked into the cell, little damage is done due to the neautral pit of the cytoplasm. If numerous lysosomes rupture simaltaneously however, the cumulative action of thier enzymes can result in autodigestion and the death of the cell.====



Digstion of Organisms
====﻿Unicellular organisms that ingest particals via vacuoles rely on intracellular digestion to prepare, the nutrients for use. The enzymes that catalyze this digestion being very protent chemicals capable of breaking down the cell substance itself are held until needed in pockets, or vesiceles called lysosomes the membrane of a lysosmes is both impermeable to the enzymes and capable of resisting thier hydroytic action.====
