Explain how the sympathetic nervous system acts to directly regulate stroke volume. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane potential where appropriate). What effect does this have on cardiac output. This will take about half a page to describe. Discuss venous return. Be sure: to define venous return and explain the importance of venous return to cardiac output. What determines venous return? Discuss each way that venous...

Based on your knowledge of cell signaling and interorgan metabolism, describe how the fuel metabolism of the liver, adipose tissue, skeletal muscle, heart and brain are affected in type I diabetics (assuming no insulin shot has been used) immediately after a meal and between meals. Include what pathways have been affected (glycolysis, glycogen synthesis, etc) and what the organ/tissue uses as a fuel source.

For Biology of Cancer- Please Explain The regulation of expression of the Ah locus, the protein products regulated by the activities of each gene, the mechanisms of AH-induced gene expression. Should be able to reason (and give an example) on how a selective or aberrant regulation of the Ah-locus might affect the predisposition to malignancies associated with exposure to AH (such as in smoking).

The proper cellular ATP levels are critical for almost all cell function (-1mM in the cytoplasm). In this problem set you will propose different mechanisms how a cell could regulate and maintain this ATP level. Your proposed mechanisms don't have to exist (do not read up online about the way cells regulate ATP levels!). But the mechanisms should be plausible and based on what you learned in...

Part 1: The basis for molecular regulation of gene expression is through base-pairing of complementary sequences. Often the sequences that are targeted are those that are critical in initiating translation (such as the Shine Dalgarno sequence and initiation codon of an mRNA). Base-pairing at these key regions blocks access of ribosomes, and in this case, translation initiation would be prevented. To help you understand...

1. What are the 2 main ways that hormones can interact with their target cells? Which chemical classes of hormones use each of the different mechanisms? Give an example of each type of hormone. 2. Hormones may interact with each other in one of 3 ways to alter body function. Describe each type of interaction and give an example of hormones involved in each one. 3. How do circulating hormones differ from paracrines & autocrines? 4. How does a portal...
