2. • Created in the ER, or Endoplasmic Reticulum and sent to
the Golgi Apparatus.
• Lysosomes are small organelles filled with digestive
enzymes.
• Located in the cytoplasm (portion of cell outside of the
nucleus) of animal eukaryotic cells
• The “janitors of the cell”
3. • Responsible for the break down of lipids, carbohydrates,
and proteins to be used by the cell
• Attach and release their enzymes, which break down the
complex sugars and proteins
• Break down organelles that are no longer useful
• Remove “junk” that may accumulate in the cell (this
prevents diseases)

5. • There are over 50 classified diseases due to Lysosomes
not functioning properly. To name a few..
-Lipidoses
-Lysosomal Transport Disease
-Glycogen Storage Disease type II
• The word Lysosome comes from two Greek words- Lysis
meaning destruction, and Soma meaning body.
• - Lysosomes contain over 3 dozen different types of
enzymes
6. What are Peroxisomes?
Small organelles found in both animal and
plant cells
Found in free floating cytoplasm
Contain at least 50 enzymes
Produce hydrogen peroxide
7. The Job of Peroxisomes
Breaking down
Enzymes in peroxisomes break down long
chain fatty acids through oxidation
Produce a great deal of metabolic
energy supplements
Abundant in organs such as the
liver, where lipids are stored, broken
down, and synthesized.
8. The Job of Peroxisomes cont.
Building up
Produce chemicals as well as breaking
them down
Make cholesterol in animal cells and
produce bile in liver cells
Contain enzymes for making
phospholipids

10. Lysosomes and Peroxisomes
Similarities
Break down
substances (fatty
acids vs.
organelles)
Built with proteins
Differences
Where they bud
(Golgi body and
ER)
Size of membrane
(peroxisomes much
smaller)
