3. Endoplasmic
Reticulums
The endoplasmic reticulum (ER) is a large, dynamic
structure that serves many roles in the cell including
calcium storage, protein synthesis and lipid
metabolism.

4. Types of ENDOPLASMIC RETICULUMS
• Smooth Endoplasmic Reticulum
• Rough Endoplasmic Reticulum
The smooth endoplasmic reticulum functions in many metabolic processes.
It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
Cells that secrete these products, such as cells of the testes, ovaries, and
skin oil glands, have an excess of smooth endoplasmic reticulum.
The rough endoplasmic reticulum has on it ribosomes, which are small,
round organelles whose function it is to make proteins.

5. Golgi Body The Golgi apparatus, or Golgi complex, functions as a
factory in which proteins received from the ER are
further processed and sorted for transport to their
eventual destinations: lysosomes, the plasma
membrane, or secretion.

6. Lysosomes
Lysosomes function as
the digestive system of
the cell, serving both to
degrade material taken
up from outside the
cell and to digest
obsolete components
of the cell itself.

7. Mitochondria
Mitochondria are membrane-bound cell
organelles (mitochondrion, singular) that
generate most of the chemical energy needed to
power the cell's biochemical reactions. Chemical
energy produced by the mitochondria is stored in
a small molecule called adenosine triphosphate
(ATP).

8. Nucleus
By housing the cell's genome, the nucleus serves
both as the repository of genetic information and as
the cell's control center. DNA replication,
transcription, and RNA processing all take place
within the nucleus, with only the final stage of gene
expression (translation) localized to the cytoplasm.

9. Ribosomes
A ribosome is an intercellular structure
made of both RNA and protein, and it is
the site of protein synthesis in the cell.
The ribosome reads the messenger RNA
(mRNA) sequence and translates that
genetic code into a specified string of
amino acids, which grow into long chains
that fold to form proteins.
