Colour TEM of primary lysosome in liver cell

Primary lysosome. Coloured Transmission Electron Micrograph (TEM) of a primary lysosome seen in a liver cell. The lysosome (red) is a membrane bound structure that contains digestive enzymes. Around the lysosome are various organelles, with the nucleus at left (yellow/green). Lysosomes are particularly prevalent in cells of the kidneys and liver. A primary lysosome contains inactive enzymes. These are activated when the membrane of the lysosome is damaged or when a substance that is to be digested enters the lysosome itself. Lysosomes can digest food brought into the cell and destroy invading organisms or cellular debris. Magnification: x18, 000 at 6x7cm size
