1. Explain how ATP is produced in the chloroplast, cytosol, and mitochondria.2. What are the roles of ATP in metabolism, transport, cell reproduction and signaling? Give specific examples for each.3. What are the different classes and subclasses of biomolecules found in the plasma membrane? Give one example for each class of membrane biomolecule, and identify the subclass of each example you gave.4. Compare and contrast transport that occurs across the plasma membrane and transport that occurs across the nuclear membrane.5. How are proteins in the secretory pathway targeted to different compartments in the cell?6. Compare and contrast the control of gene expression in prokaryotic and eukaryotic cells.7. Describe the structure, formation, and function of the three cytoskeletal elements.8. What are the similarities and differences among the different stages (prophase, metaphase, anaphase and telophase) of mitosis, meiosis I and meiosis II?9. Explain the roles of GPCRs and RTKs in controlling glucose levels in the blood by describing the events that occur during glucagon and insulin signaling.10. What are the similarities and differences between the extrinsic and intrinsic pathway of apoptosis.11. What are protein kinases and why are they important?12. What are G proteins? Give examples of G proteins and describe their functions in the cell?13. Describe the structure and function of different proteins found in the extracellular matrix.14. What are proteins, lipids, carbohydrates and nucleic acids?15. Describe three different ways of regenerating NAD+ in the cytosol.16. What are the different components of the electron transport chain and describe how electrons are transferred from NADH to oxygen.17. What is the role of integrins and cadherins in the interaction of cells with the extracellular matrix and with other cells? What types of cell surface structures are they part of? How are these cell surface structures similar and different from one another?18. How does the cell distinguish among proteins destined to the mitochondria, chloroplast, cytosol, peroxisome, nucleus and endoplasmic reticulum?19. Name the different motor proteins that associate with cytoskeletal elements and describe their functions.20. What is chromatin? Describe the different types of chromatin and how they are formed.21. What are histones? How are they modified? How does histone modification influence gene expression?22. What are ubiquitin ligases? What are their roles in controlling gene expression and the cell cycle?23. What are the differences between prokaryotic and eukaryotic DNA?24. What is the difference between tumor suppressor genes and oncogenes? Give an example of each and describe their roles in carcinogenesis.25. How can the study of the cell cycle and cell signaling help in the treatment of cancer?
A hurricane in Caribbean devastates a small isolated island, destroying all but about a dozen of once dominant turpentine trees on the island.
You measured the purified protein concentration, which is 5 ug/uL. You decided to load 20 ug protein to the gel. How would you dilute your sample?
Some dogs bark when trailing, others are silent. The barking trait is due to a dominant gene. Erect ears are dominant to drooping ears. What kinds (phenotypes) of pups would you expect from a heterozygous erect-eared barker mated to a droop-eared,..
Calculate the standard free energy change for the conversion of D-glucose from alpha to beta form at 40 degrees C, if relative amount of alpha-glucose at this temperature is 36%.
what is measured when looking at the net change in displacement of the potato sample?
Explain why some drugs used to treat type 1 diabetes are compounds that diffuse into the cell and activate tyrosine kinases. Why might they not be as effective in the treatment of type 2 diabetes?
Explain how it is possible that Brad has two mutated CFTR genes when no one else in his family has cystic fibrosis.
How do you describe the apparent contradictory finding of spontaneous pain and interference with pain perception in just about the same area.
Food poisoning can be caused by a variety of microbes. Determine which of the following pairs is incorrect? Group B Streptococcal disease include.
Think of the beaver's digestive organ system. Clarify its overall role. List several of the organs in this system, describe how each functions, and outline how organs work together to carry out the role of the organ system.
