)(n.) An imaginary memory area supported by some operating systems (for example, Windows but not DOS) in conjunction with the hardware. You can think of virtual memory as an alternate set of memory addresses. Programs use these virtual addresses rather than real addresses to store instructions and data. When the program is actually executed, the virtual addresses are convertedinto real memory addresses.
To accomplish the tasks associated with digestion, the lysosomes use some 40 different types of lysosomal enzymes, such as glycosidases, protease, acid phosphatases, sulfatases and lipases.Lysosomal enzymes are synthesized in the endoplasmic reticulum and modified in the Golgi apparatus.ysosomal Enzymes.

1 Lysosomes are the main sites of digestion, that is the break-down of structures, within cells. 2  There are, however, some circumstances (diseases/conditions) in which lysosomes begin to 'break-down' living cells-not just useless parts of cells or potentially harmful structures.0nm to 1 Î¼m Â§ , lysosomes have a single outer membrane consisting of a phospholipid bilayer and contain acid hydrolases which are enzymes capable of breaking-down macromolecules. Â§ i.e. 50x10-9m to 1x10-6m, which is the same as 0.00005 to 0.001 mm (millimetres).
