Question

1. humans share several enzymes with thermophilic bacteria. the word thermophilic means “heat - loving”. using the graph to the left, explain why you think this type of bacteria is called thermophilic. at what temperatures does the enzyme denature? explain how you know.

Explanation:

Enzymes denature at high - temp. Thermophilic bacteria thrive in heat as seen from their enzyme activity graph. Humans and thermophiles share enzymes as shown.

Answer:

Enzymes denature at high temperatures above their optimal range. Thermophilic bacteria are called so as their enzymes show high activity at high temperatures (e.g., around 50°C). Humans and thermophiles share enzymes which may have similar functions but different optimal temperature ranges.
