Catalyst remembering 9 11
Catalyst: “Remembering 9/11”

  • Where were you when you found out about the terrorist attacks on the world trade center? How did you feel? Have your feelings about the incident changed?


Cell parts protein synthesis
Cell Parts: Protein Synthesis

  • DNA (Deoxyribonucleic Acid):

    • “Master blueprint”, genetic code

      • Prokaryotic: DNA in nucleoid

      • Eukaryotic: DNA in nucleus


Cell parts protein secretion
Cell Parts: Protein Secretion

  • Vesicles containing proteins are not transported across the cell membrane by previously learned mechanisms.


Cell parts protein secretion1
Cell Parts: Protein Secretion

  • ncbn

Exocytosis: the process of exporting materials out of the cell via a vesicle

“Outside”

Endocytosis: the process of importing materials into the cell via a vesicle

“Inside”

Vesicle: a small molecule within a cell enclosed by a lipid bilayer

Cell Parts: Protein Synthesis

Nuclear Pore

Nucleus

  • Transcription & Translation: DNA instructs the synthesis of a protein.

    • Nucleolus synthesizes ribosome

    • Ribosome attaches to rough E.R.

    • RNA copies DNA (Transcription)

    • RNA travels through nuclear pore to ribosome

    • Ribosome decodes RNA into a protein (Translation)

    • Protein travels through rough E.R. to fold into a complex 3D shape

    • Protein travels to Golgi where it is packaged into a vesicle

    • Vesicle travels to plasma membrane & is secreted through exocytosis

Nucleolus

RNA

Rough E.R.

Ribosome
