Under each of the following conditions, please predict the effect the mutation will have on the rate at which glycolysis will proceed in liver cells: a. Loss of the allosteric site for ATP in phosphofructokinase b. Loss of binding site for citrate in phosphofructokinase c. Loss of the phosphatase domain of the bifunctional enzyme that controls the level of fructose 2,6-bisphosphate d. Loss of the binding site for fructose 1,6- bisphosphate in pyruvate kinase.

Suppose a new cancer therapy is being tested in a large clinical trial. The therapy is working well; it seems that it is extending the lives of patients suffering from a deadly form of cancer. But the results are not yet statistically significant and there’s a small chance the extended lives is just a coincidence. The trial is stopping so that those who are not getting the therapy – those in the control arm – can be given the new therapy, so everyone can benefit. The physician-researchers directing the trial claim that stopping the trial before it provides statistically-significant data – before they can prove the drug is really the reason people are living longer – might in fact delay the therapy’s wider use (for example, getting FDA approval). Evaluate the moral implications of stopping the new cancer therapy versus the moral implications of continuing it. Be explicit in your use of the moral principles in your answer.

This part of the vertebrate nervous system is often called the second brain because it can function independently, its neurons are organized in microcircuits that contain afferent neurons that respond to local stimuli to integrate information and coordinate motor output, and has its own glial support cells.

a. somatic nervous system

b. enteric nervous system

c. autonomic nervous system

d. efferent division

e. sympathetic nervous system
