Cellular Respiration Rate Lab In this activity simple activity, students read a brief background on cellular respiration and Bromothymol blue as an indicator. BTB changes color toward yellow in the presence of an acid. Bromothymol Blue Cellular Respiration Lab. Yeast, brom thymol blue (BTB) and a sugar solution are placed in a cuvette. clock or stopwatch. As a result, an acid-base indicator such as bromothymol blue (btb) can be used to indicate the presence of carbon dioxide. Without exercise: … By the end of this lab, students should be able to Describe how the pH indicator, bromothymol blue, can detect the presence of CO 2. Purpose: We can measure cellular respiration utilizing an indicator known as Bromothymol blue (BTB). Respiration also produces waste products including carbon dioxide and water, which are the same substances that served as raw materials for photosynthesis. In this lab, we will identify the role of carbon dioxide production, breathing rate, and heart rate in determining the rate of cellular respiration. How are cellular respiration and photosynthesis alike? Purpose/Question: Does exercise have any effect on the rate of cellular respiration? Write the equation for cellular respiration.
