10. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins.

11. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins.
• The nucleus stores genetic information. The
instructions for your proteins.

12. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins. (continued)
• Ribosomes use the instructions to link amino acids in the
correct sequence to form proteins.
– Amino acids are the monomers of larger proteins.Amino acids are the monomers of larger proteins.

13. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins.
• Many processes occur in the endoplasmic reticulum.
Network of channels, further modification of proteins.

14. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins.
• There are two types of endoplasmic reticulum.

15. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins.
• There are two types of endoplasmic reticulum.
– rough endoplasmic
reticulum
Proteins
– smooth endoplasmic
reticulum
Makes lipids

16. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins. (continued)
Golgi Apparatus – like the
post office or UPS. It sorts,
packages, and delivers
proteins.

17. 3.2 Cell Organelles
Several organelles are involved in making and
processing proteins. (continued)
• Vesicles are membrane-bound sacs that hold materials
like proteins.

18. 3.2 Cell Organelles
Other organelles have various functions.
• Mitochondria supply energy to the cell.

19. 3.2 Cell Organelles
Other organelles have various functions.
• Vacuoles are fluid-filled sacs that hold materials.

20. 3.2 Cell Organelles
Other organelles have various functions.
• Lysosomes contain enzymes to digest material.

21. 3.2 Cell Organelles
Other organelles have various functions.
• Centrioles are tubes found in the animal cells.
– Centrioles help divide
DNA.

22. 3.2 Cell Organelles
Plant cells have cell walls and chloroplasts.
• A cell wall (made of cellulose) provides rigid support.
• Chloroplasts convert solar energy to chemical energy.
