Feedback Control of Hormone Secretion Quiz

Play an AI-generated podcast conversation about this lesson

What type of control mechanism is primarily responsible for ensuring a proper level of hormone activity at the target tissue?

Neutral feedback mechanisms

Feedback mechanisms are not involved in hormone regulation

Negative feedback mechanisms (correct)

Positive feedback mechanisms

In the context of hormone secretion, what role do conditions or products resulting from the action of the hormone play?

Enhance further release of the hormone

Have no effect on hormone secretion

Suppress further release of the hormone (correct)

Convert hormones into different types

At which levels can feedback regulation of hormones occur?

Only at the level of target tissue activity

Only at the level of hormone synthesis

Only at the level of gene transcription

At all levels, including gene transcription and synthesis steps (correct)
