Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A hormone secreted by the pancreas that enhances the uptake of glucose by cells, thus lowering blood glucose levels.
A
medulla
B
insulin
C
histamine
D
hormone
Explanation: 

Detailed explanation-1: -After docking to its receptor on muscle and adipose tissue, insulin enables the insulin-dependent uptake of glucose into these tissues and hence lowers blood glucose levels by removing the exogenous glucose from the blood stream (Figure 2).

Detailed explanation-2: -Glucagon is a peptide hormone secreted from the alpha cells of the pancreatic islets of Langerhans.

Detailed explanation-3: -Glucagon increases blood sugar levels, whereas insulin decreases blood sugar levels. If your pancreas doesn’t make enough insulin or your body doesn’t use it properly, you can have high blood sugar (hyperglycemia), which leads to diabetes.
