Hormonal coordination in humans
Question
- A. Only those tissues have receptors that bind the hormone
- B. Only those tissues contain blood vessels
- C. Only those tissues can make glucose from glycogen
- D. Only those tissues are controlled by the nervous system
Answer
The correct option is Only those tissues have receptors that bind the hormone. This is the best answer because it directly matches the learning objective to apply knowledge of target organs to explain why hormones affect only specific tissues.
Explanation
The correct option is Only those tissues have receptors that bind the hormone. Only those tissues have receptors that bind the hormone supports the answer because it fits Human endocrine system in Hormonal coordination in humans and uses the required AQA GCSE Biology context. The objective asks students to apply knowledge of target organs to explain why hormones affect only specific tissues, so the explanation must connect the option to that exact skill or idea. The other options are incorrect because "Only those tissues contain blood vessels", "Only those tissues can make glucose from glycogen", "Only those tissues are controlled by the nervous system" do not match the specific approved objective or practical context.
Common mistake
Misunderstanding Target Organs
Students often think that hormones affect all tissues in the body equally, rather than specific target organs.
Emphasize that hormones are like keys that only fit specific locks (target organs), and review examples of hormones and their corresponding target organs to reinforce this concept.
