What harmful substances in the body, produced as a result of inflammation, can damage cells?

Antioxidants
Enzymes
Free radicals
Hormones

The correct answer is: Free radicals

Free radicals are harmful substances produced in the body, especially as a result of inflammation. These highly reactive molecules can damage cells by altering their structure and function. Free radicals seek out electrons from other molecules to stabilize themselves, which can lead to a chain reaction of damage. This oxidative stress caused by free radicals is known to play a significant role in the development of various diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders. Understanding the nature of free radicals helps in recognizing the importance of antioxidants, which can neutralize these harmful substances. Antioxidants work by donating electrons to free radicals without becoming unstable themselves, thus preventing cellular damage. Enzymes and hormones, while essential for numerous body functions, do not inherently act as damaging agents like free radicals can during inflammatory processes. Therefore, free radicals are specifically recognized for their detrimental effects in the context of inflammation and cell damage.
