flat = = =Cellular Respiration annotations= Use the following document to annotate notes. Be sure to not just answer a question, but either search out the answer, connect information to either other chapter or other information within the notes, etc.

=Yeast Respiration lab= All organisms need to carry out the process of respiration to obtain energy to complete their life processes and activities. Various factors also affect how efficient an organism is at carrying out respiration. In this investigation, you will try to determine how yeast carries out respiration. Discuss as a group the factors that could effect respiration in yeast. Add the factors your group discussed to your team wiki page. We will test one factor: amount of sugar (sugar concentration). What is the dependent variable? What is the independent variable?

Part I Making bread (each person does this): Mix 6-8 Tbs. flour with 2 Tbs. of warm water, 20 ml of sugar solution (fill small tube to the top), and 1 g. of yeast. (Suggestion: Put flour on plate, make a well in the center, add yeast, and then pour warm water on top of the yeast. Add the sugar solution.) I will come around and add oil and salt. Mix the contents on a paper plate and knead in extra flour to remove stickiness. Form into a ball and place in a muffin tin (make sure your name is on the bottom - of the tin, of course.) Cover with a warm towel. Let rise for an hour and then we will bake at 360 until brown. **Be sure to take pictures.**

Part II Measuring yeast activity (make one set up for your group): Use the same sugar solution you used in making the bread. Add 20 ml of sugar solution, 1/2 tube warm water, and 1.0 g. yeast to a test tube. Shake the tube until the yeast is dissolved. Place a balloon over the top of the tube. Make an observation after 10 minutes and again after 20 minutes. Note the depth of the bubbles created as well as the expansion of the balloon. **Be sure to take pictures.**

Calculations:

Radius: r = C/2π Volume : V = 4/3 2πr3 (r3 is radius cubed)

Graphing: Think about how you want to graph the data. You will need to include all of the group/class data in the graph(s). Use an online graphing program such as: [] or google docs or excel.

Analysis: 1. State 2 clear, concise conclusions derived from the analysis of the results from the experiments in your class. 2. What was the dependent and independent variables in the experiment? Explain. 3. According to the experimental data, what kind of environment do yeast prefer? How did the sugar concentration change the result? Explain. 4. How did the amount of rising change with the different types of sugar solutions used? 5. What kind of respiration did the yeast carry out in the experiment? Explain.
