According to the table, what is the effect of sugar on the rate of cellular respiration?
A student wanted to compare the rate of cellular respiration in yeast cells by measuring the amount of carbon dioxide produced. She placed 5 g active dry yeast in each of five test tubes, then added water and sugar as outlined in the table below. She placed a rubber stopper with a hole on each test tube, then inserted a syringe into the hole to capture the gas released. The table shows her experimental setup and the data collected:
The rate of cellular respiration decreases with the amount of sugar added.
The amount of sugar has no effect on the rate of cellular respiration.
There is not enough information to determine the answer.
The rate of cellular respiration increases with the amount of sugar added.
