1. By exhaling out carbon dioxide into the straw on top of the bromothymol blue indicator, the solution will turn the color blue into a yellowish-green color. When there is a presence of something that is acidic the BTB indicator changes its color into yellow/green. So in this case, the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well.
2. By exercising more, one’s body requires more energy in their muscles. As the exercise becomes more continual, the aerobic respiration is primarily needed. Due to aerobic respiration there is an increase in oxygen intake and more carbon dioxide is released which provides energy for one’s body. (Metabolic is elevated)
3. In a person’s body that exercises, the lungs are important in sending more oxygen to the person’s cells, because the body consumes all available resources. The person’s body takes in oxygen quicker as they exercise, resulting in the person breathing harder/faster to keep up with the rate consumption.
4. During exercise, the oxygen enters into the bloodstream leading to the lungs and the cells take in the oxygen (capillary sacs). As the blood flows through the body, it transports the good blood and gets
My hypothesis was, if one exercises more, that one’s body will produce more CO2 since the body has to gain more energy from the cellular respiration cycle. My hypothesis was proven correct throughout the procedure because. As the exercise increases, the person’s heart/breathing rates were much higher than when the person rests. Thus, the more oxygen is pumped to the blood, than the body makes more energy, which than release more carbon dioxide. To create more energy, a person needs more oxygen, therefore the person’s heart pumps more oxygen to the blood and the breathing increases harder/deeper. By not creating enough oxygen, lactic acid would be created instead, which causes pain and becoming
