Functions/Structures of Organelles

Lysosomes start working when a cell absorbs or eats food. They attach and release enzymes once the material is in the cell and those enzymes break down complex molecules like sugars and proteins. Even if there is no food in the cell, they will work because once the signal to do so is sent out, they won't stop. Lysosomes will end up digesting the cell organelles for nutrients.


Lysosomes are connected with other parts of a cell. The lysosomes contain the enzymes that are created in the rough endoplasmic reticulum. The enzymes are "packaged" and sent to the golgi to do the final work of creating digestive enzymes. The golgi pinches off a very small and specific vesicle which is the lysosome.
