i) What are the functions of liver, skeletal muscle, adipose tissue and heart muscle? Don’t forget the endocrine functions of some of these tissues.

ii) Relate the functions of liver, skeletal muscle, adipose tissue and heart muscle to the dominant metabolic pathways in these tissues. NOTE! , not all pathways take place in all tissues.

iii) What hormones have effects on these tissues and what receptors do they bind to in liver, skeletal muscle, adipose tissue and heart muscle? Also what are the effects of these hormones on these tissues? Include specifics about pathways and specific enzymes of pathways that are affected .

iv) What metabolic pathways are most active and what are the preferred fuels of these tissues in the fed (high blood glucose) state, under mild fasted (low blood glucose) and under starvation conditions (very low and prolonged low blood glucose concentrations) of liver, skeletal muscle, adipose tissue and heart muscle?

explain how the second control point (fru16bp to fru 6p) of gluconeogenesis is regulated in response to low levels of glucose in the blood. describe how the pertinent enzyemes and metabolites are regulated by covalent and allosteric mechanisms in response to hormone stimuli. 10 pt answer.

1. You just ate a McDonalds meal deal and your blood glucose levels are soaring. Your pancreas releases an important hydrophilic hormone into the blood in order to deal with these high glucose levels.

Which ribosomes get… (er system secontory pathway)

What is the hormone released by the pancreas and how can liver cells respond to it? (be as detailed as possible)

2. What are two processes that can happen using the glucose that gets taken up by the liver? In order for your liver to take up this excess glucose there must be an increase of transmembrane glucose transports (GLUT4 transporter) on the plasma membrane of the liver. If the glut4 transporter is nonfunctional or if levels on the plasma membrane are decreased, blood glucose levels will be abnormally high. Describe four specific mutations in the protein targeting of glut4 that could cause abnormally high levels of glucose. (The translation of the glut4 messenger RNA by the ribosome is normal.)
