AP Biology

Design and complete a hands-on lab experiment to identify factors that influence the rate of respiration in yeast and to test a factor influencing the rate of respiration by using the materials below:

• bottle – screw-on lid (such as a baby bottle or water bottle)

• clay, modeling

• container or bowl, large (to hold water)

• container, tall narrow (such as a baby bottle or water bottle)

• container, tall narrow

• drill or sharp tool (approximately the same diameter as the tubing)

• Lab Notebook

• marker

• stopwatch or clock with second hand

• sugar (1 teaspoon)

• tablespoon

• tubing, flexible – 24 inches long

• water • yeast (1 teaspoon)

Optional:

• chemicals for adjusting pH (acidic = vinegar / lemon juice, basic = baking soda / sweeteners)

Include your procedures, any steps, datd collected. Use graphs/tables to record/present your data if necessary.

Solution

The factors which influence respiration in yeast are -

Sugar undergoes metabolism and produce ATP which is required for growth of yeast.
