This is BIOchemistry) For the appetite-related signaling molecule MELANOCORTIN:

a.) What is the specific function of that molecule?

b.) What is the mechanism of that action (how does it do what it does)?

c.) How is that molecule made? Describe any prepro- and pro- forms and associated cleavages or covalent bonds or phosphorylations associated with the molecule.

d.) Describe how the molecule is regulated

(This problem relates to chapters 22, Biosynthesis of amino acids, nucleotides, and related molecules; and chapter 23, hormonal regulation and integration of mammalian metabolism, from the Lehninger Biochemistry textbook).

Why is it difficult for scientists to predict the rate of warming that Arctic regions will experience?

What does “semi-discontinuous” DNA replication mean? Explain in words how the lagging DNA strand is replicated in bacteria. What specific enzymatic activities does DNA polymerase I have? Name each activity and explain its role in DNA replication. If DNA polymerase I lacked its 3’-5’ exonuclease activity, what specific consequences with respect to DNA replication would be observed? What consequences would be observed if, instead of DNA pol I, DNA polymerase III lacked its 3’-5’ exonuclease activity? Explain your answers.

A) Define mutualism in general and differentiate between obligate and facultative mutualisms. Give examples.

B) Discuss some plant-plant, plant-animal, animal-animal mutualisms

A) Discuss plant strategies to avoid herbivory

B) Compare and contrast sit-and-wait foragers to active foragers

Explain in words what the ubiquitination reactions are and how they function. What are the ubiquitination enzymes, where are they used in the pathway and what are their function? Explain how proteins starting with an acidic amino acid are recognized for ubiquitination (no structures needed).

A patient who is diabetic decides to go on the beef jerky diet. She eats almost nothing other than beef jerky and similar dried meat products. She does drink plenty of water and gets vitamin supplements. Describe how her body reacts to the diet. Be sure to list any concerns you might have about the diet and the person's health. (This problem relates to chapters 22, Biosynthesis of amino acids, nucleotides, and related molecules; and chapter 23, hormonal regulation and integration of mammalian metabolism, from the Lehninger Biochemistry textbook).
