Peroxisomes are dependent on hydrogen peroxide for their functions, so an enzyme deficiency
that results in an inability to form hydrogen peroxide would likely result in an inability to digest
very long chain fatty acids. These fatty acids would build up in peroxisomes until most of the
cellular contents were displaced by oversized peroxisomes. This would ultimately result in cell
death.
A child is diagnosed with an enzyme deficiency that prevents the production of hydrogen
peroxide. What would the likely outcome be of such a deficiency?
1.) Microfilaments: polymerized rods of Actin
2.) Microtubules: hollow polymers of tubulin
3.) Intermediate filaments: differ by cell type but include keratin, desmin, vimentin, and lamins
, What are the predominate proteins in each cytoskeletal element?
Centrioles consist of nine triplets of microtubules around a hollow center, while flagella consist
of nine doublets on the outside, with two microtubules on the inside.
How do the cytoskeletal structures of centrioles and flagella differ?
1.) Connective tissue
2.) Epithelial tissue
3.) Epithelial tissue
4.) Connective tissue
5.) Connective tissue
Classify each of the following cells as epithelial cells or connective tissue:
1.) Fibroblasts, which produce collagen in a number of organs.
2.) Endothelial cells, which line blood vessels.
3.) Alpha-cells, which produce glucagon in the pancreas.
4.) Osteoblasts, which produce osteoid, the material that gardens into bone.
5.) Chondroblasts, which produce cartilage.
Eukaryotic flagella contain microtubules composed of tubulin, organized in a 9+2 arrangement.
Bacterial flagella are made of flagellin and consist of a filament, a basal body, and a hook.
How do the structures of eukaryotic and prokaryotic flagella differ?
Yes, yes, no, no
