Question

temperature (°c) product formed (mg) 10 5 20 15 30 25 40 22 50 10 a group of students conducted an experiment to the optimum temperature for this enzyme is around 30°c, beyond which activity decreases. enzyme activity continues to increase steadily with temperature. the enzyme becomes more stable at higher temperatures, making the reaction faster. the enzyme functions best at 10°c and stops working at higher temperatures.

Explanation:

We analyze the data: at 10°C, product is 5 mg; 20°C, 15 mg; 30°C, 25 mg; 40°C, 22 mg; 50°C, 10 mg. So enzyme activity (product formed) increases up to 30°C then decreases.

• The purple option says activity increases steadily with temp, but data shows decrease after 30°C, so wrong.
• The orange option says enzyme is more stable at higher temps (faster reaction), but product decreases at 40/50°C, so wrong.
• The teal option says best at 10°C, but 30°C has more product, so wrong.
• The green option says optimum around 30°C, beyond which activity decreases, which matches the data (product peaks at 30°C then drops).

Answer:

The optimum temperature for this enzyme is around 30°C, beyond which activity decreases.
