This week, we discussed the important processes of photosynthesis, cellular respiration, and fermentation. We wrote equations for photosynthesis and respiration, and discussed how each process depended on each other. We did a lab to demonstrate cellular respiration in yeast cells. In this experiment, we determined whether adding different amounts of sugar would affect the carbon dioxide production of yeast cells. We used balloons to "catch" the carbon dioxide that was being released from the process, and we measured the circumference of each balloon to determine how much gas was produced.
Next week, we will continue our discussion of mitosis and apoptosis. We will relate this discussion to cancer, which is a result of these processes not working properly.
