What is the effect of the mixture of yeast with sweaters on the amount of carbon dioxide released?
Introduction:
The purpose of this lab was to see how much carbon dioxide was released when we mixed yeast with different sweeteners. We made this lab because we knew that when yeast use energy, they break down high energy molecules like sugar to get the energy they need and release carbon dioxide as a reaction. Yeast has two kind of respiration: aerobic respiration, which consists of oxygen like humans and anaerobic respiration, it is a cellular respiration that does not need oxygen and yeast perform a fermentation.
The characteristics of living things are that living things are made of cells, obtain and use energy, grow and develop, reproduce, respond to their environment and adapt to their environment. I know that humans are alive because human have cells; they use energy and obtain energy (ex, sugar);
They grow and …show more content…
Hypothesis:
If we mix yeast with sweeteners then carbon dioxide will release in the balloon. I predict that honey will released the most carbon dioxide.
Results:
As a result, the yeast did not release carbon dioxide as much as we expected to and my prediction was correct, the tube with honey inflated the most. The balloons all started at 11 cm. For tube 1, which was our control (yeast and water) stayed the same for 20 minutes as well as tube 2, which contained yeast, water and spandex. For tube 3, which had yeast, water and honey changed at 16 minutes from 11 cm to 13 cm. Finally tube 4, which involved yeast, water and corn syrup changed at 16 minutes from 11 cm to 12 cm.
