What waste product of yeast respiration is useful in making bread explain how it makes bread rise. Carbon dioxide. It makes bubbles in the dough. Yeast can take out more energy from sugar when oxygen is present in their environment. But in the absence of oxygen, yeast switch to an alternative pathway that does not require oxygen but still makes energy. This process is called fermentation. With fermentation, yeast can still get energy from sugar, but less energy is made from each sugar. Yeast makes tiny gas bubbles in our in bread before it gets baked. This experiment demonstrates cellular respiration when the yeast consumes the sugar and releases carbon dioxide. Materials: A packet of yeast (available in the grocery store) A small, clean, clear, plastic bottle (16 oz. or smaller) 1 teaspoon of sugar. The hypothesis in the beginning of this experiment was that various carbohydrates have different rates of respiration by a yeast culture raised on glucose. The differences in time for respiration to peak for the other sugars were due to enzyme regulation called induction. This is the time required for the glucose fed yeast culture to alter its. In this lab, you will try to determine whether yeast are capable of metabolizing a variety of sugars. When yeast respire aerobically, oxygen gas is consumed and carbon dioxide, CO 2, is produced. You will use a CO 2 Gas Sensor to monitor the production of carbon dioxide as yeast respire using different sugars.
