Question
Insulin functions by facilitating the uptake of glucose by: (1 Point)a) Liver cellsb) Muscle cellsc) Fat cellsd) All of the above
Solution
d) All of the above
Insulin is a hormone that plays a crucial role in managing the body's energy supply. It is produced by the pancreas and released when any of the food groups (carbohydrates, proteins, and fats) are ingested.
-
Liver cells: Insulin stimulates the liver to store glucose in the form of glycogen. A large proportion of the glucose absorbed from the small intestine is immediately taken up by hepatocytes, which convert it into the storage carbohydrate glycogen.
-
Muscle cells: Insulin also facilitates the uptake of glucose into muscle cells. The glucose is then stored as glycogen or used for energy.
-
Fat cells: Insulin promotes the uptake of glucose and the synthesis of fats in adipose tissue. When insulin levels are high, excess glucose is converted into fatty acids, which are then stored as triglycerides in adipose tissue.
So, insulin facilitates the uptake of glucose by liver cells, muscle cells, and fat cells. Therefore, the answer is d) All of the above.
