)(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.
The two types of lysosomes are Peroxisomes which is a vesicle containing oxidases and catalase. It's located by the smooth ER of the animal cell.The second type of lysosme is the Proteasome which is a tiny barrel-shaped structure that contain proteases.ysosomes are distributed among different types of eukaryotic cells  by their level of nutrients. Cells processing a high quantity of  larger nutrients will generally have m â¦ ore lysosomes than other  cells.
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).
