Professors instructions: In lab you selected a pathogen to create a case study. As you write your case study think about how you can give enough information to allow your fellow students to identify the pathogen without making it too easy. Several diseases have similarities in their presentation so you […]

A neuron with an intracellular Cl- concentration of 50 mM is placed in a solution that contains 100 mM Cl- at 25 degree celcius. The membrane potential of the neuron is -60 mV. Assuming the neuronal cell membrane has channels that allow facilitated diffusion of Cl-, do you expect Cl- […]

You are studying a set of mouse genes whose expression increases when cells are exposed to the hormone cortisol, and you believe that the same cortisol-responsive transcriptional activator regulates all of these genes. Which of the following statements believe should be TRUE if your hypothesis is correct? A. The cortisol-responsive […]

In addition to protein phosphorylation and dephosphorylation, protein degradation also plays key role in regulating signal transduction pathways and cell proliferation. Please answer the following questions: (1). Please give one example to describe how protein degradation regulates signal transduction pathway; (2) Please give another example to describe how protein degradation […]
