Question

qn 19 a biotechnology company develops a genetically engineered enzyme that functions optimally at 90°c and is used to break down waste in industrial reactors. which claim provides the strongest scientific and ethical justification for this enzymes use? it will automatically increase biodiversity by speeding up decomposition. it may reduce industrial waste safely because it can function in extreme environments without harming natural enzymes. it could permanently alter human enzymes to withstand high temperatures. it should replace natural enzymes in all organisms to improve global efficiency.

Explanation:

Enzymes typically work best at specific temperatures. If an enzyme has an optimal temperature of \(90^{\circ}C\), it means it can function in high - temperature industrial reactors. This allows for waste breakdown in such extreme (high - temperature) environments. Natural enzymes might not withstand these high temperatures. So, the engineered enzyme's ability to work at \(90^{\circ}C\) (a high temperature) is a key scientific and ethical justification as it can operate in industrial settings that natural enzymes can't.

Answer:

It may reduce industrial waste safely because it can function in extreme environments without harming natural enzymes.
