A person is asked to run on a treadmill for two hours so data can be gathered on how lactic acid accumulates in the human body. The results are placed in the table below.
Using the information in the table, determine how the respiration of the person has changed throughout the run.
The data shows that the cells started with anaerobic respiration, but changed to aerobic respiration when the oxygen level increased in the body.
The data shows that the cells started with aerobic respiration, but changed to anaerobic respiration when the oxygen level increased in the body.
The data shows that the cells started with aerobic respiration, but changed to anaerobic respiration when the oxygen level decreased in the body.
The data shows that the cells started with anaerobic respiration, but changed to aerobic respiration when the oxygen level decreased in the body.
A teacher set up a demonstration with 5 fermentation flasks filled with the solutions listed in the chart. She added 10 ml of yeast solution to each flask, and students observed the flasks every 10 minutes for the rest of the class period.
