What varibles has the least direct effect on the rate of an enzyme-regulated reaction?
Carbon Dioxide concentration
What might decrease global atmospheric carbon dioxide?
There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.
Does carbon dioxide increase the greenhouse effect?
Yes. Carbon dioxide is a greenhouse gas. When we increase its atmospheric concentration, as we do by burning fossil fuels, it causes an enhanced greenhouse effect, leading to global warming.
What is an increase in the atmospheric levels of carbon dioxide is the biggest contributor?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
What are large amounts of atmospheric carbon dioxide absorbed by?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
The atmospheric concentration of carbon dioxide is regulated by?
Plants play the biggest role in regulating the amount of carbon dioxide in the atmosphere. They do so by using it during photosynthesis and release oxygen.
Why has the concentration of carbon dioxide in the air changed?
Because the atmospheric CO2 concentration is part of the "Carbon Cycle" and biological and geological processes therefore affect it.

What Large amounts of atmospheric carbon dioxide are absorbed by what?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
Is it true that increased levels of atmospheric carbon dioxide are largely due to the increased amount of aerobic respiration by plants and animals?
No. This is part of the carbon cycle, which is a closed system and does not increase or reduce the atmospheric concentration of carbon dioxide. The only way to increase the level of atmospheric carbon dioxide is to bring carbon from outside that system. Volcanic eruptions can add a relatively small amount, but the main source of new carbon is from burning fossil fuels, such as coal, oil and natural gas.
How does the carbon cycle keep the amount of carbon dioxide constant in the atmosphere?
In pre-industrial times, the amount of carbon dioxide (CO2)that animals breathe out was matched by the amount absorbed by plants, so that the concentration of atmospheric carbon dioxide remained remarkably stable in the range of 260 to 280 parts per million (ppm) over a very long period. Adding additional carbon dioxide by burning fossil fuels, overwhelms the carbon cycle and causes the atmospheric concentration of carbon dioxide to rise beyond this range. Deforestation can break the carbon cycle, first by removing a store of carbon which will be released as additional carbon dioxide into the atmosphere, and in some cases by reducing the ability of nature to absorb carbon dioxide from the air.
What is the relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide?
The relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide is that when there is a rise in atmospheric carbon dioxide the warmer the temperature of the ocean is
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.
What is an increase in the atmospheric levels of carbon dioxide is the biggest contributor?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
What are large amounts of atmospheric carbon dioxide absorbed by?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
