Science (086) — AI-generated practice question

When we eat a meal, blood sugar (glucose) levels rise. The pancreas detects this rise and secretes the hormone insulin into the blood. Insulin signals body cells to absorb glucose, converting it to glycogen, thereby lowering blood sugar levels back to normal.

Once blood sugar returns to the normal level, the pancreas receives this information and reduces insulin secretion. This self-regulating process — where the output (lowered blood sugar) controls the further secretion of the hormone — is called the feedback mechanism.

• The examiner wants three clear points: (1) stimulus — blood sugar rises, (2) response — insulin is secreted, (3) feedback — normal sugar level switches off insulin secretion.
• Use the term feedback mechanism explicitly; it is the key term in the question.
• Keep the example of the meal and blood sugar central throughout — don't give a generic answer.
• The source passages confirm hormones are regulated by a feedback mechanism; insulin/blood sugar is the standard textbook example for this concept in Chapter 6.
