The student repeats the experiment with glucose at 10, 20, 30, and 40 C. CO2 production rate (mL/min) is plotted.
Which conclusion is best supported?
- A
Lower temperatures produce more CO2
- Bcheck_circle
Yeast fermentation has an optimal temperature near 30 C
- C
Yeast fermentation increases linearly to 40 C
- D
Yeast cannot ferment at any temperature
Explanation
The fermentation rate rises from 10 to 30 C and falls at 40 C, indicating an optimum near 30 C. Above the optimum, enzymes (and likely cells) begin to denature.
