Question

negative feedback loop
what occurs within a negative feedback system?
hormone levels have no effect on additional production of that hormone.
as hormone levels decrease, further hormone release is inhibited.
as hormone levels rise, further hormone release is promoted.
as hormone levels rise, further hormone release is inhibited.

Explanation:

Negative feedback loops work to maintain homeostasis. When hormone levels rise, the system detects this change and inhibits further release of that hormone to bring levels back to normal. The first option is incorrect as hormone levels do affect production in a feedback loop. The second option is wrong because when hormone levels decrease, in a negative feedback loop (for hormones like those regulated to maintain a certain level), release would be promoted (not inhibited) to raise levels. The third option is incorrect as rising levels should inhibit (not promote) further release in a negative feedback loop.

Answer:

As hormone levels rise, further hormone release is inhibited.
