Which organ in the body detects changes in blood glucose levels?

• liver

• stomach

• pancreas

• small intestine

Answer explanation

The pancreas detects changes in blood glucose concentration and secretes hormones in response to regulate blood glucose levels.

Name the hormone that is secreted if blood glucose levels are too high.

• glucagon

• glycogen

• insulin

• starch

Answer explanation

The pancreas secretes insulin when blood glucose levels are too high; it causes blood glucose levels to decrease.

Match each word to the correct definition.

• glycogen

• an organ or tissue that produces and secretes substances

• gland

• a stored form of glucose found in liver and muscle cells

• hormone

• a chemical substance, produced by a gland, that travels in the blood

• glucose

• a sugar that travels in the blood and used for respiration

Answer explanation

Hormones are secreted from glands to bring about an effect on the body. Glucose is a sugar that is a reactant in respiration and needs to be supplied to most cells of the body. Glycogen is a store of glucose found in liver and muscle cells.

What are carbohydrates broken down into during digestion?

• amino acids

• fatty acids

• enzymes

• sugars

Answer explanation

Carbohydrates are broken down into simple sugars (e.g. glucose) when they are digested.

Which of the following cause an increase in blood glucose concentration?

• exercising

• eating a meal

• fasting

Answer explanation

Eating a meal will cause an increase in blood glucose concentration.

What changes does insulin bring about in the body?

• glucose stops being absobed by the liver

• more glucose is absorbed by the liver and stored as glycogen

• blood glucose concentration increases

• blood glucose concentration decreases

Answer explanation

Insulin acts on the liver to increase the amount of glucose absorbed and causes glucose to be converted into glycogen and stored in the liver and muscle cells.
