Lysosomes contain about 50 different degradative enzymes that can hydrolyze proteins, DNA, RNA, polysaccharides, and lipids. read more
These pumps hydrolyze ATP and pump H+ into the lysosome lumen to acidify it. Other co and counter ions move across the membrane to maintain a voltage gradient. To degrade nutrients that the cell uptakes, the lysosomes fuse with endosomes. read more
Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides. read more
