In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor’s DNA, thus killing its cells. For one patient, it is desired that 0.10 JJ of proton energy be deposited in a tumor. To create the proton beam, the protons are accelerated from rest through a 23 MVMV potential difference. What is the total charge of the protons that must be...

You have previously used radiation therapy to induce cell apoptosis in a mouse tumor model in which FGF is over-expressed. Recently, you notice that this therapy is no longer effective and the tumor continued to grow rapidly. Genomic sequencing revealed that those tumor cells have acquired a new loss-of-function mutation in the tumor-suppressor gene Pten, whose protein product normally acts as a phosphatase to dephosphorylate PIP3 into PIP2. Based on this information, you have an idea of why the tumor...
