Previous problemNext problem

Verified step by step guidance

Understand the role of antioxidants: Antioxidants are molecules that help protect the body by neutralizing free radicals, which are unstable molecules that can cause cellular damage.

Learn about free radicals: Free radicals are atoms or molecules with unpaired electrons, making them highly reactive. They can damage cells, proteins, and DNA through oxidative stress.

Recognize how antioxidants stabilize free radicals: Antioxidants donate electrons to free radicals, effectively stabilizing them and preventing them from causing further damage.

Eliminate incorrect options: 'Destroying' is not accurate because antioxidants do not destroy free radicals; they neutralize them. 'Copying' and 'Cooling down' are unrelated to the mechanism of antioxidants.

Select the correct answer: Based on the mechanism of action, the correct term is 'Stabilizing,' as antioxidants stabilize free radicals by donating electrons.
