)(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.

Lysosomes are membrane bound organelles that are found in the cytoplasm of both plant and animal cells. The word lysosome was derived from two Greek words, 'lysis' which means destruction or dissolution and 'soma' which means 'body'. Lysosomes were discovered in 1949, by a Belgian cytologist, Christian de Duve.ysosome Structure. Lysosomes are actually membranous sacs filled with enzymes. They are found in all eukaryotic cells and act as 'garbage disposal' or the 'digester' of the cell.
