3 types of vesicles are released from the Golgi Complex i) Membrane vesicles : transport proteins to the plasma membrane ii) Transport vesicles : transport proteins to cell organelles iii) Secretory vesicles : transport proteins out of the cell (breast feeding)
7. Lysosomes
Lysosomes are vesicles formed by Golgi Complex that contain digestive enzymes for recycling, cleanup and digestion of bacteria and cell debris.
2 functions of lysosomes:
i) Autophagy : worn out organelles are digested, and the digested parts are returned to the cytosol for future use (recycling – ex: liver cell recycles 50% of its contents each week. ii) Autolysis : lysosomes degrades and destroys whole cell (self destroy).
**Some Lysosomes work outside of the cell – sperm head**
8. Peroxisomes
Peroxisomes are similar in structure to lysosomes and are responsible for the removal of hydrogen atoms from organic molecules, a process called oxidation . A by-product of oxidation is hydrogen peroxide. Example: they oxidize toxic substances like alcohol.
