Yeast cells use sugars to undergo the chemical reactions of cellular respiration. We will test the ability of yeast cells to sucrose as an energy source for cellular respiration. We will examine if various concentrations of sucrose have an effect on cellular respiration and whether the temperature also plays a role in cellular respiration.

**Answer these questions based on the video posted:**

Using this data table, graph the data from the experiment in the video:

| Amount of Foam in the Yeast Experiment |
| --- |
| **Time** | **20°C/RT** | **30°C** | **40°C** | **50°C** | **60°C** |
| 0 min | 0cm | 0cm | 0cm | 0cm | 0cm |
| 10 min | 1.5cm | 4cm | 11cm | 6cm | 3cm |
| 20 min | 2.5cm | 9.5cm | 17cm | 11cm | 9cm |
| 30 min | 4.5cm | 13cm | 18cm | 10cm | 11cm |

Using the data presented in the video for the yeast experiment, draw a line graph. There are time points shown - 0, 10, 20 and 30 minutes. Plot a line graph of the foam level(s) for each temperature versus time (Time is on the x-axis in minutes while the amount of foam (in cm) is on the y-axis). All 4 line graphs should be on the same graph paper. Make sure to properly label each graph.

1. **The variables that are controlled for in this experiment are ____ . Select all that apply.**
   - A. Not shown in the video
   - B. Amount of water
   - C. Amount of yeast
   - D. The size of the bottle
   - E. The temperature of the water
