25. Describe all the different places that you could find a lipid bilayer in the cell. Things to know and think about – Cell structure and function: 1. Compare and contrast prokaryotic and eukaryotic cells (i.e. how are they similar and how are they different?). What are some examples of each type of cell?

-the two are different in that Eukaryotic cells have a nucleus, many of them are multi-cellular unlike prokaryotic cells and they are much bigger that prokaryotic cells 2. What are the three domains of life and what kinds of organisms make up those groups? Which are prokaryotic and which are eukaryotic? 3. Describe what chromosomes (supercoiled DNA) are typically like in prokaryotes and eukaryotes. Where are chromosomes located in each type of cell? 4. What is a cytoplasm? 5. Describe the physical structure, general location, and function of the following structures: cell wall, chloroplast, cytoskeleton, extracellular matrix, Golgi apparatus, lysosome, mitochondria, nucleus, peroxisomes, ribosome, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole. 6. What would happen if a cell lacked lysosomes? or peroxisomes? or mitochondria? 7. Compare and contrast microtubules, intermediate filaments, and microfilaments (i.e. how are they similar and how are they different? Where might you see these structures and what are their functions?). 8. What is a motor protein and why is it important? What other structures in the cell does it “interact” with? 9. Describe the different ways that cells stay connected to each other and explain how those connections differ between plant and animal cells? 10. Explain how different cells (both adjacent and more distant) communicate with each other. What advantage is there for cells (both near and far) to communicate with each other? 11. Describe a signal. What is its function? What molecules are typically utilized as signals? What are some examples of a signal? 12. Describe the general concept of signal transduction. What kind(s) of response(s) might occur after a signal? Lipids – made of hydrocarbons, phospholipids, testosterone, long term energy storage, double bonded= unsaturated Carbs- mono/disaccharide, energy storage, glucose, starch, sucrose, H-C-OH Protein- H,N,C,O amino acid, transfer, enzymes, cytoskeletons, peptide bonds Nucleic acids- DNA/RNA, genetic information

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
