Question
Which of the following statements is true for pancreas ?Group of answer choicesThe alpha cells of the pancreas secrete insulin.Hypersecretion of insulin causes diabetes mellitus.Insulin causes an increase in the blood sugar level.Glucagon and insulin are antagonists of each other.
Solution
The statement "Glucagon and insulin are antagonists of each other" is true for the pancreas.
Here's why:
-
The pancreas contains alpha and beta cells. Alpha cells produce glucagon, while beta cells produce insulin.
-
Insulin and glucagon have opposite effects on blood sugar levels. Insulin decreases blood sugar levels by promoting the uptake and storage of glucose in cells. On the other hand, glucagon increases blood sugar levels by promoting the breakdown of glycogen into glucose for use by the body.
-
Therefore, insulin and glucagon work in opposition to each other to maintain blood sugar levels within a normal range. This is why they are considered antagonists.
The other statements are incorrect because:
- The alpha cells of the pancreas secrete glucagon, not insulin. Insulin is secreted by the beta cells.
- Hypersecretion of insulin does not cause diabetes mellitus. In fact, diabetes mellitus is often caused by insufficient insulin production or the body's inability to properly use insulin.
- Insulin does not cause an increase in the blood sugar level. It actually helps to decrease blood sugar levels.
