When you exercise the energy demand is higher and so respiration rate is higher. Respiration = Glucose + Oxygen --> Water + Carbon dioxide (+energy). So higher respiration rate, more carbon dioxide
Carbon dioxide
Your body is an engine that uses fuel (food) to produce energy for you to do exercise. The fuel contains carbon from the carbohydrates you eat, and the body uses oxygen from the air to do a chemical reaction that combines the carbon with the oxygen to produce energy plus carbon dioxide. If you do exercise, you use more fuel and more oxygen, and you produce more carbon dioxide. The body has sensors that detect excess carbon dioxide in the blood, and they make you breathe faster to get rid of it.
The amount of carbon dioxide a person produces
Sorry not sure could be because of the amount of carbon dioxide blood increases?
carbon dioxide :p
Treadmills operate by muscle force. Muscles are powered by the conversion of sugars to energy and carbon dioxide. More energy is used and more carbon dioxide is released when people exercise. People exhale the carbon dioxide. So treadmill use results in the emission of more carbon dioxide than would be released by a person at rest.
Respiration :)
The carbon dioxide level fluctuates during a single year due to seasonal changes in plant growth and decay, which affect the amount of carbon dioxide absorbed and released into the atmosphere.
Forest fires increase the amount of carbon dioxide in the atmosphere
carbon dioxide
No, the amount of oxygen in the atmosphere is much greater than the amount of carbon dioxide. The current levels of carbon dioxide are approximately 0.04% of the atmosphere, while oxygen levels are around 21%.
The amount of carbon dioxide exhaled is always greater than the amount inhaled because part of the oxygen inhaled is converted into carbon dioxide by metabolic processes of digestion, while any carbon dioxide inhaled remains unchanged in the body and is always exhaled again.
