The Dark Side of Oxygen

Oxygen is vital for energy production in cells but also causes damage over time, contributing to aging and diseases like cancer. Free radicals, a byproduct of oxygen, can harm DNA. Antioxidants in fruits and vegetables help neutralize free radicals, offering protection against oxygen damage.

What is the primary function of mitochondria in the body's cells?

• To produce free radicals

• To eliminate waste from the cells

• To harness oxygen to create energy

• To store oxygen for later use

How does oxygen contribute to the aging process?

• By enhancing the immune system

• By damaging cells through its corrosive nature

• By causing the body to produce more cells

• By increasing the body's energy levels

What are free radicals, and why are they harmful?

• They are stable molecules that help in digestion

• They are reactive particles that can damage DNA

• They are proteins that build muscle

• They are antioxidants that protect the body

What role do antioxidants play in the body?

• They increase the production of free radicals

• They help in the absorption of oxygen

• They neutralize free radicals

• They store energy for later use

Which dietary choice can help protect the body from oxygen damage?

• A diet high in proteins

• A diet low in carbohydrates

• A diet rich in fruits and vegetables

• A diet high in processed foods
