please help with my ochem extra credit!
Extra Credit Assignment Glioblastoma multiforme (GBM) is a highly lethal brain cancer. Uncontrolled proliferation of glial cells in neural tissue is the primary cause of GBM, and this activity has been attributed to the glial cell membrane protein vascular endothelial growth factor receptor (VEFGR). This protein is a high-affinity tyrosine kinase receptor for growth factor ligands. A genetic mutation causes overexpression of this protein. This overexpression may cause increased glial cell response to...

Please explain the mechanisms!
1. Propose a synthesis for each of the following problems starting with reagent shown and using any other organic or inorganic reagents allowed in each problem. Multiple steps are required. The number of steps you use does not matter. Reactions should give the desired product as a major product. For full credit show the product of each step (reaction). If you make use of organometallic reagents such as Grignard, Wittig, organolithium, organosodium, organocopper, etc. you must...

All of these problems should be done by hand. You may use a computer or calculator to find roots of polynomials with constant coefficients. All hand calculations can of course be verified with a computer. Show calculations for asymptote angles, center of mass, angles of departure, etc. for full credit. 3. Consider the proportional control system with measurement dynamics in Figure 2. (a) (5 points) - Determine the limiting value of gain K for a stable system. (b) (5 points)...
