Document Summary

Intricate complex of membranous organelles and vesicles that move materials into the cell from outside, from inside to outside, and within the cell. Transport of proteins, lipids, and other cellular materials. Modification, packaging, and secretion of materials (often proteins). Intracellular digestion of biomolecules that are no longer needed. Cell is a dynamic structure where things are always bring synthesized and broken down. Maintain an acidic environment by pumping protons into their interior via active transport. Organelles involved in genetic control of the eukaryotic cell. Remember: nucleus has a membrane, nucleoid does not. Sire of dna synthesis, transcription (dna rna). May be attached to er (forms rer) or free in the cytoplasmic matrix. Proteins made on ribosomes of rer are often secreted (or inserted into er membrane as integral membrane proteins). Site of tricarboxylic acid cycle (tca) activity (krebs cycle) Some intracellular parasites don"t need mitochondria because they mooch off of their host"s mito.

Complete the following sentences to examine various components of the endomembrane system.

Information within the ____________ is transcribed into mRNA and transported outside the nuclear envelope.

Proteins, which are synthesized by ____________ , are then released into the ____________ , where they are further folded and modified.

The ____________ does not have attached ____________ and produces lipids, such as steroids.

Once proteins are folded and modified, transport vehicles called ____________ pinch off and surround them with membranes to be transported elsewhere.

The vesicles are moved to the ____________ where they are sorted and packaged.

Transport vehicles called ____________ carry the macromolecules to the ____________ where they fuse and release their contents to the outside environment.

ribosomes

Golgi apparatus

smooth endoplasmic reticulum

vesicles

plasma membrane

rough endoplasmic reticulum

nucleus

secretory vesicles

One effective learning strategy when trying to learn largeamounts of factual information is to group items, or âchunkâ. Youshould include all important structures of the cell (this includescell membrane and membrane adaptations as well as organelles).Examples of general categories could be location, function,morphology, etc. Your categorization groups must tell the viewersomething about the structures. Once your structures are groupedaccording to the characteristics they share, you should include ashort phrase about what differentiates them from each other withinthe group. Citation of your source material must be present.

List of Organelles:

Nucleus, Nuclear envelope/membrane, Nucleolus, Ribosomes,Endoplasmic reticulum, Golgi apparatus, Mitochondria, Plasmamembrane, Cytoskeleton, Transport/secretory vesicles,Phagosomes/endosomes-including sorting & recycling endosomes,Lysosomes, Peroxisomes, Lipid droplets, Glycogen granules

I started this assignment and was going to go withfunction and morphology. Below is what I have so far, but I'mhaving a difficult time coming up with a short phrase for each anddistinguishing between the organelles that can change shape/morphand those that cannot. I am open to changing the categories that Ihave chosen to chunk. I've never used this technique before so it'sa new concept for me.

Function

Protein Synthesis â Nucleus, Nuclear envelope, Nuclear porecomplex, Ribosomes, Rough endoplasmic reticulum, Golgi apparatus,Plasma membrane

Energy Production â Mitochondria, Lipid droplets, Glycogengranules

Transportation â Transport vesicles, Phagosomes,Cytoskeleton

Metabolism â Lysosomes aid in digestion, Peroxisomes oxidizefatty acids

Morphology

Ability to change shape â Mitochondria, Cell membrane, Nuclearenvelope,

Inability to change shape â Nucleus, Nuclear envelope,
