A study of fermentation by yeast is an interesting extension of AP* Biology Lab 5 Cell Respiration. It also offers possible tie-ins to Lab 1 Diffusion and Osmosis and Lab 2 Enzyme Catalysis. In this activity, students measure the rate at which yeast ferments solutions of differing sucrose concentrations and apply the results to common […]
