Quick explanation

Describe (HT only) thyroxine as a hormone from the thyroid gland that stimulates basal metabolic rate

  • This point belongs to Hormonal coordination in humans, especially Feedback systems (HT only).
  • You need to be able to describe (HT only) thyroxine as a hormone from the thyroid gland that stimulates basal metabolic rate.
  • The key ideas to know are basal metabolic rate, thyroxine, and HT only.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Feedback systems (HT only) to exam-style questions, flashcards, and revision notes for Hormonal coordination in humans.

Quick student answer

How does (HT only) thyroxine work?

Direct answer

In Biology, this page helps you answer questions about (HT only) thyroxine within Hormonal coordination in humans. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are thyroxine and basal metabolic rate.

Key terms

  • thyroxine: A hormone produced by the thyroid gland that regulates metabolism and stimulates the basal metabolic rate.
  • basal metabolic rate: The rate of energy expenditure per unit time by endothermic animals at rest in a neutrally temperate environment.

Common trap

Thyroxine Function Misunderstanding: Focus on understanding that thyroxine primarily regulates metabolism, while its effects on growth and development are secondary. Clarify the specific functions of thyroxine in metabolic processes.
