Question
Students are studying respiration in yeast and constructed the setup pictured in the diagram. They allowed the system to run over the course of 10 minutes and collected data in 2 minute increments. They repeated the set up three times with different temperatures.

What question are the students testing and what is a plausible prediction for their experiment with yeast?
A.
What is the effect of temperature on the rate of aerobic respiration in yeast cells? Prediction: The limewater will become more cloudy over time due to carbon dioxide production.
B.
What is the effect of temperature on the rate of anaerobic respiration in yeast cells? Prediction: The limewater will become more cloudy over time due to the production of carbon dioxide.
C.
What is the effect of temperature on the rate of cellular respiration in yeast cells? Prediction: The limewater will become cloudy over time due to use of oxygen in the process.
D.
What is the effect of temperature on the rate of photosynthetic respiration in yeast cells? Prediction: The limewater will remain clear due to the consumption of carbon dioxide in the process.

The correct choice is:
**B. What is the effect of temperature on the rate of anaerobic respiration in yeast cells? Prediction: The limewater will become more cloudy over time due to the production of carbon dioxide.**
**Explanation:** Yeast typically undergoes anaerobic respiration (fermentation) when oxygen is not available, producing carbon dioxide and ethanol. The setup described with limewater is likely used to detect the production of carbon dioxide, which would make the limewater cloudy. The question focuses on how temperature affects the rate of this anaerobic process, making option B the most appropriate choice.
