Activity #39: Cells Alive


Today students examined the similarities between human cells and yeast cells. Students learned about cellular respiration. We used BTB solution which is blue when oxygen is present and yellow if carbon dioxide. When yeast carry out respiration, it is in a anaerobic environment where yeast break down sugar and release energy and carbon dioxide which is a waste product. When carbon dioxide is released, the solution turns yellow.

Students also took the 3rd quiz for unit C today!
