)(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.
Lysosomes digest excess or worn-out organelles, food particles, and engulf viruses or bacteria. The membrane around a lysosome allows the digestive enzymes to work at the 4.5 pH they require. Lysosomes fuse with vacuoles and dispense their enzymes into the vacuoles, digesting their contents. They are created by the addition of hydrolytic enzymes to early endosomes from the Golgi apparatus. The name lysosome derives from the Greek words lysis, to separate, and soma, body.
