Distance Learning: Yeast Cellular Respiration

Learn all about yeast and how it uniquely functions with this Distance Learning: Yeast Cellular Respiration kit!

In this experiment, students will expose living yeast cells to three different sugars-glucose, sucrose, and lactose. The yeast cells should begin to utilize the sugars as a food source if they are capable of metabolizing them, and will begin to engage in aerobic respiration and/or fermentation.

This activity allows students to understand that yeast may use different options for energy production, with varying degrees of effectiveness. A pH indicator will be used to indirectly determine the effectiveness of the three different sugars as a food source for the yeast.

This kit is in alignment with NGSS HS-LS1-7 and HS-LS2-3!
