What effect does exercise have on the amount of carbon dioxide released by the blood?

Answer 1

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

Answer 2

Carbon Dioxide builds up during exercise because it is a by-product of aerobic respiration. When you exercise your body needs to respire more in order to supply the working muscles with energy. You therefore produce more carbon dioxide.

Answer 3

Exercise affects your breathing through many different ways.

Depending on the type of exercise (e.g. long distance, or sprinting) it could change the type of breathing that occurs.

For example, for short, fast running distances, you will switch to anaerobic respiration (glucose -> energy + lactic acid)

Exercise also quickens your breathing rate, and you take longer, quicker breathes.

If you exercise for a long time, your breathing rate will increase even more, until you are at your maximum uptake of oxygen/air.

Answer 4

when you exercise your cells will need more Atp to keep your muscles working good, therfore your body will increase on oxygen by making you breather faster or deeper. The amount of carbon dixode the cell produces will also increase.

Answer 5

All the time you are using your respiratory system.

The respiratory system takes the oxygen that you inhale and the glucose/sugar you eat through the body by being pumped through the bloodstream. Then when the oxygen and glucose reach your cells they react, causing them to create water, energy, and carbon dioxide.

When you are exercising your body needs more exercise so the heart works harder to get the oxygen and glucose/sugar to your cells to make more energy so that you can keep exercising. Whenever you make energy you make carbon dioxide. So when you are exercising you need more energy and when you create more energy you create more carbon dioxide.

Answer 6

the more you exercise the more carbon dioxide you produce as the metabolic activity of the muscle increases. the substrate which the muscle is using will also affect the CO2 production.

Answer 7

as the carbon dioxide level rises, nervous impulses from the breathing center causes the diaphragm to contract, bringing air into the lungs
