What is the function of antioxidants in biotechnology?

• A. To enhance the growth rate of plants
• B. To protect cells from damage caused by oxidative stress
• C. To improve the efficiency of reproduction in organisms
• D. To aid in the fermentation process

Answer: (B)

Antioxidants play a critical role in protecting cells from damage caused by oxidative stress, which is the result of an imbalance between free radicals and the body's ability to detoxify these reactive products. In biotechnology, antioxidants are utilized to safeguard plant, animal, and microbial cells from oxidative damage during various processes, including genetic engineering and tissue culture. This protection is vital because oxidative stress can lead to cell death and disrupt metabolic functions, ultimately affecting growth, development, and the viability of biotechnological applications.

Their protective function helps maintain the integrity of cellular components, such as DNA, proteins, and lipids. By mitigating oxidative damage, antioxidants help ensure the stability and productivity of biotechnological processes, thus enhancing the overall effectiveness of research and applications in this field.
