  • The Carbon Cycle NASA Earth Observatory

    The Fast Carbon Cycle. The time it takes carbon to move through the fast carbon cycle is measured in a lifespan. The fast carbon cycle is largely the movement of carbon through life forms on Earth, or the biosphere. Between 10 15 and 10 17 grams (1,000 to 100,000 million metric tons) of carbon move through the fast carbon cycle every year.

    C 4 carbon fixation is one of three biochemical processes, along with C 3 and CAM photosynthesis, used to fix carbon. It is named for the 4carbon molecule present in the first product of carbon fixation in the small subset of plants that use that process, in contrast to the 3carbon molecule products in C 3 plants.

    Life had remained energetically limited until the widespread availability of oxygen. This breakthrough in metabolic evolution greatly increased the free energy supply to living organisms: today, more than 10 17 kcal of free energy is stored annually by photosynthesis on earth, which corresponds to the fixation of more than 10 10 tons of carbon into carbohydrates and other organic compounds.

    Carbon fixation is a process found in autotrophs (organisms that produce their own food), usually driven by photosynthesis, whereby carbon dioxide is changed into organic materials. Carbon fixation can also be carried out by the process of calcification in marine, calcifying organisms such as Emiliania huxleyi .

    In plants, carbon dioxide (CO 2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of lightindependent reactions of photosynthesis. These reactions actually have ...
