Which of the following compounds is most soluble in hexane (CH3CH2CH2CH2CH2CH3)?

What is self-plagiarism? Define this term.

Many professors do not teach during the summer. Thus, when they are not on contract, the professors may not check his or her email.

Many students find college classes difficult. Especially during the summer semester.

Many students on campus love to go eat at Leannas, they like to call in their orders and pick up their lunch.

The flux or the amount of glucose that is broken down in the glycolysis pathway is primarily controlled by the regulation of the enzyme phosphofructokinase I (PFK I). This enzyme is strongly activated by AMP and inhibited by citrate. A) Briefly explain why these two compounds are good choices for regulation of PFK I. (2 pts.) AMP: Citrate: B) The enzyme phosphofructokinase II (PFK-2) coverts fructose-6-phosphate to fructose-2,6-bisphosphate, which is a potent activator of phosphofructokinase I (PFK-1). The activity of PFK-2 is regulated by PKA phosphorylation. Is the kinase activity of PFK-2 activated or inhibited in the liver in response to epinephrine? (1 pt.)

What is the advantage gained by the glutamatergic cell in shuttling lactate when it appears that a pyruvate shuttle would be more direct?  (1 pt.) What role does Ala play in the shuttle system? Again, it appears that shuttling pyruvate would be more direct, since you start with pyruvate in the glutamatergic cell and end up with pyruvate in the astrocyte.  (1 pt.) Write out the reaction that takes 2-oxoglu, which is another name for
