Question

In order to maintain homeostasis, the pancreas secretes two hormones to keep blood sugar levels within a normal range. Which of the following statements correctly describe the negative feedback mechanisms used to control blood sugar levels? Mark all that apply After eating a candy bar, glucagon is released from the pancreas in response to rising glucose levels. Without eating for several time units, the pancreas releases glucagon in response to decreased glucose levels. After eating a candy bar, insulin is released from the pancreas in response to rising glucose levels. 1 Without eating for several time units, the pancreas releases glucagon in response to increased glucose levels.

Explanation / Answer

Option 2nd and 3rd are correct. After eating a candy bar, the level of glucose in blood increased and pancrease releases insulin in response to this increased level of glucose. Insulin decreases the level of glucose in blood. Without eating for several time units causes a decrease in blood glucose level and pancrease releases glucagon in response to this decrease in blood glucose level. Glucagon increases the level of blood glucose.

Note: The action of glucagon and insuline is opposite.
