Question

insulin-stimulated glucose uptake and utilization by skeletal muscle and liver cells results in a reduction in the blood glucose level. which organ is primarily responsible for the decrease in serum glucose, and why? choose one: a. the skeletal muscle is responsible for the majority of glucose uptake, as skeletal muscle cells have more glucose receptors than liver cells. b. the skeletal muscle is responsible for the majority of glucose uptake, as the total mass of skeletal muscle is greater than the mass of liver cells. c. the liver is responsible for the majority of glucose uptake, as liver cells can store more glycogen than muscle cells. d. the liver is responsible for the majority of glucose uptake, as liver cells have more glucose receptors than skeletal muscle.

Answer 1

The skeletal muscle is primarily responsible for the decrease in serum glucose due to its larger mass compared to liver cells, leading to higher glucose uptake and glycogen storage in muscle tissue.

Step-by-step explanation:

Insulin-stimulated glucose uptake and utilization by skeletal muscle and liver cells result in a decrease in the blood glucose level. The organ primarily responsible for the decrease in serum glucose is skeletal muscle, as the total mass of skeletal muscle is greater than the mass of liver cells. This allows skeletal muscle to account for the majority of glucose uptake. Insulin facilitates this process by increasing the number of glucose transporters on the muscle and liver cell membranes, making these tissues more efficient at absorbing glucose from the bloodstream. Once inside these cells, glucose is converted into glucose-6-phosphate, maintaining a concentration gradient that favors continued glucose entry into the cells. Moreover, insulin stimulates glycogen storage in both liver and muscle cells, but muscle cells constitute a larger reservoir for glycogen due to the larger volume of muscle tissue in the body.
