What is the main role of insulin in glucose (carbohydrate) metabolism?
 
  a. Conversion of complex carbohydrates into glucose
  b. Movement of glucose from blood into the cells
  c. Prevention of kidney excretion of glucose
  d. Prevention of the formation of fat cells

Question 2

How does the glucose we eat influence metabolism?
 
  a. It combines with the glucose we make to form the proteins needed to replace those lost daily in stool.
  b. It is composed of extra or empty calories that are not necessary for life and only contribute to obesity.
  c. It is used inside cells to form the high energy substance adenosine triphosphate (ATP) needed to perform most cell functions.

Answer to Question 1

B
Many body cells have membranes that do not allow glucose to move into the cells to participate in metabolism. When insulin binds to membrane insulin receptors, the membranes become more open to glucose, allowing it to enter.

Answer to Question 2

C
Although both proteins and fats can make fuel to run the body's actions, the main fuel provider is carbohydrate. We eat carbohydrates as sugars and starches. Once inside the digestive tract, the body converts most of the carbohydrates we eat into glucose (also called dextrose). Glucose is the most common simple carbohydrate and the main fuel for the human body. Inside cells, glucose is used to form ATP, which is the main chemical energy substance that drives all the body's cellular reactions.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
