Why does adrenaline help make more glucose available from the liver during fear?
Answer and explanation
Correct answer: So that muscles can get immediate energy
The governing concept is the emergency or fight-or-flight response. Fear activates the adrenal glands, and adrenaline helps the liver break down stored glycogen, making more glucose available in the blood. This rapid energy supply supports vigorous muscle activity and immediate action, so option A is correct. Root growth toward water and leaf movement away from light are plant responses, while stopping thyroxine production is not the purpose of adrenaline; hence B, C, and D are distractors.
