Blood with a high glucose concentration is passed through living liver tissue. Insulin is added to the blood before it enters the tissue.
Which result would show that the liver tissue is responding to the insulin?
The glucose concentration is higher in the blood leaving the tissue, and the amount of glycogen in the liver tissue increases.
The glucose concentration is lower in the blood leaving the tissue, and the amount of glycogen in the liver tissue decreases.
The glucose concentration is lower in the blood leaving the tissue, and the amount of glycogen in the liver tissue increases.
The glucose concentration is higher in the blood leaving the tissue, and the amount of glycogen in the liver tissue decreases.
