Question

One of the hormones is GIP (glucose-dependent insulin trophic peptide), which stimulates the secretion of insulin. It is secreted by cells of the duodenum in response to the presence of glucose. Its secretion and action on insulin production is an example of a:a. homeostatic positive feedback mechanism amplifying the response to glucose ingestion.b. homeostatic negative feedback mechanism, keeping a system near a set point.c. homeostatic negative feedback mechanism changing the set point.d. this response is not homeostatic.

Answer 1

The correct answer is option- b. homeostatic negative feedback mechanism, keeping a system near a set point.

Explanation:

Homeostasis is a resistance system of the body that balances the body according to the change to maintain equilibrium in the system or body. It can take place with negative or positive feedback.

The negative feedback mechanism is the action that opposes to cue or stimulus presented by the system. For example, GIP is the hormones that help in the increase in insulin release and suppress the release of glucagon. It also prevents the blood sugar hike by slow emptying of gastric.

Thus, the correct answer is - B. homeostatic negative feedback mechanism, keeping a system near a set point.
