90% of cancer cells have active telomerase enzymes. How does this play a role in cancer and how they divide fast.

What is the difference between type 1 and type 2 diabetes and which one is more prevalent in today’s society? What are the name of the cells that secrete glucagon in the pancreas and what is glucagon’s function? 7.What is the name of the gonad for the male and female, respectively?

explain what is the difference between glycolysis in cancer cells ( The Warburg Effect) vs normal cells and how do you think this will impact the cells overall metabolism?
what does telomerase enable cancer cells to do the normal adult somatic cells cannot do?
What drives the formation of the pseudopods that move cancer cells? Towards what does it drive them?
What effect does Epinephrine and Glucagon have on the activity of adenylyl cyclase in adipose cells? What are three different mechanisms for lowering blood glucose that result from insulin binding to its receptor?
Depletion of cholesterol in the cell membrane using a drug (mevastatin) has been associated with apoptosis in cancer cells. a. What effect would cholesterol depletion have on the integrity of lipid rafts in the membrane? b. Researchers found that FAS death receptor was activated in cholesterol depleted cancer cells. Explain how activation of this receptor activates killer caspases. c. When a caspase is converted from its inactive to its active form there are changes in the primary and tertiary structure...
1.In general, this site is discussing sequencing surrounding “driver” mutations in cancer cells. What do these mutations do to cancer cells as opposed to the “passenger” mutations also frequently seen in cancer cells 2. You presented the nucleotide sequence you recorded from the autoradiograph in class in question #1 and assigned directionality to your sequence. Explainyour reasoning for assigning each end as 5’ or 3’
How does cancer cells EMT promote resistance? What role does the immune micro environment play?
Chemists are able to kill cancer cells by adding an adamantyl group to a drug that binds cancer-promoting proteins. a) How does the large greasy adamantyl group effect the surface of the protein? What does it mimic? b) What other proteins or cellular systems will respond to this “sign” on the protein surface?
