Discussion:
Physiology: Fat Cell Responses, Blood Oxygen, Insulin Levels
Give detailed paragraph or more explanation to all questions:
1) A fat cell responds to the presence of the harmone epinephrine by increasing cytosolic cyclic AMP Production, which leads to the catabolism of both glycogen and fat; what is the best explanation for this phenomenon?
2) After spending several days at a high altitude, where oxgen pressure is low, a person will begin to produce more red blood cells, which enhances the ability of his/her blood to carry oxygen to the tissues. Which control mechanism of the body best describes this response? Explain?
3) The harmone insulin enhances the transport of glucose into most of the body's cells. Its secretion is controlled by a negative feed-back system between the concentration of glucose in the blood and and cells that secrete insulin. Is it because a decrease in blood glucose concentration will stimulate insulin secretion, which will in turn lower the blood glucose concentration still further. Explain your answer?
