When blood sugar decreases, the glycogen in the liver is converted into which substance?

A. Liver

The liver plays a central role in metabolizing carbohydrates, fats, and proteins, maintaining blood glucose levels, and detoxifying harmful substances.

B. Pancreas

The pancreas produces enzymes and hormones like insulin but is not the main site for detoxification or nutrient metabolism.

C. Gallbladder

The gallbladder’s primary function is to store and concentrate bile, not metabolize nutrients or detoxify substances.

D. Salivary glands

Salivary glands initiate digestion by producing enzymes like amylase, but they do not play a role in metabolism or detoxification.

A. Smoking cigarettes regularly

Smoking introduces harmful chemicals that significantly increase oxidative stress and the production of free radicals, which damage cells and contribute to chronic diseases like cancer and cardiovascular disease.

B. Consuming a diet rich in fruits and vegetables

Fruits and vegetables contain antioxidants that neutralize free radicals and help reduce their damaging effects.

C. Engaging in regular moderate physical activity

Moderate physical activity actually reduces oxidative stress over time by enhancing the body’s antioxidant defenses.

D. Getting 7–9 hours of sleep each night

Adequate sleep supports immune function and reduces oxidative stress. Lack of sleep—not healthy sleep—is more likely to increase free radicals.
