Yeast is a microorganism that is commonly used to make bread and beer. Yeast must respire to survive. Respiration is a reaction that occurs in the cells of living thing, and is controlled by specific enzymes.

Some students planned a simple experiment to find out how temperature affects respiration in yeast. The students collected the carbon dioxide produced during respiration in a balloon. They suggested the following hypothesis;

How does temperature affects the rate of respiration in yeast as measured by the volume of carbon dioxide produced in 15 minutes?

The set up for the experiment is shown below;
