Presentation Transcript

  1. 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?

  2. Cell Parts: Protein Synthesis • DNA (Deoxyribonucleic Acid): • “Master blueprint”, genetic code • Prokaryotic: DNA in nucleoid • Eukaryotic: DNA in nucleus

  3. Cell Parts: Protein Secretion • Vesicles containing proteins are not transported across the cell membrane by previously learned mechanisms.

  4. 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 Image Source: http://karimedalla.files.wordpress.com/2012/09/i60_0322.jpg

  5. 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 DNA Nucleolus RNA Rough E.R.
