Exam 19: Metabolic Integration

Which of the following functions by specifically targeting neuronal control of food consumption?

Compare the activation levels of AMPK signaling in a normal-weight versus an obese person in response to adiponectin exposure.

Glucagon stimulates glucose export by increasing metabolic flux through gluconeogenesis in the

PPARs have a variety of functions in lipid metabolism that include all EXCEPT

Which of the following changes in metabolic flux would be expected to occur during long periods without food?

Most fad diets do not work because

Whipple surgery, sometimes carried out on patients battling pancreatic cancer, is one of the most demanding surgeries to perform. It involves removing parts of the pancreas and rerouting aspects of the digestive track. A complication of the surgery can be the development of diabetes. Why could this complication develop? Include the types of cells and hormones that are involved.

A physician believes her patient has metabolic syndrome. In her examining room, she checks the patient's visceral fat levels and blood pressure. She then writes out a prescription for the patient to obtain bloodwork. The bloodwork includes a glucose tolerance test. What additional bloodwork should the physician order for the patient?

Which of the following is unlikely to affect metabolic homeostasis?

The numerical value of a food that indicates how quickly glucose is released into the blood is called the

Analysis of phosphorylated proteins in a cell with a fully active AMPK would reveal that is phosphorylated.

A patient presents with insulin resistance, hypertension, and hyperlipidemia. What condition would you diagnose this patient as having?

Orlistat and olestra can both lead to undigested lipids in the colon, yet they do so by contrasting mechanisms. Orlistat __________, whereas olestra _.

The blood-brain barrier results from , which allow glucose and to enter the brain.

Neuronal samples from wild-type mice were monitored in the absence and presence of leptin via Western blotting. The data are shown below. Choose the answer that correctly identifies the NPY/AGRP neuronal samples obtained in the absence and then the presence of leptin.

Which of the following drugs stimulate adrenergic receptor signaling?

Which organ is responsible for regulating physiological levels of glucose?

What is the process of maintaining optimal metabolic concentrations and managing chemical energy reserves in tissues? Describe the three primary factors that influence this process.

Liver and skeletal muscle both respond to insulin by exhibiting an increased metabolic flux through glycolytic and glycogen synthesis pathways. Yet the tissues also exhibit different responses in how glucose is transported into the cells on insulin stimulation. What are these differences?

Anorexigenic neurons express the receptor.
