Carbon dioxide in photosynthesis

The agarophyte has been shown to take up carbon in this fashion. It has carbonic anhydrase both inside the organism and out. Inhibiting either of these types of carbonic anhydrase greatly decreases photosynthesis, but adding an anion transport inhibitor does not. Adding TRIS buffer to the extracellular fluid (seawater) also has no effect (the purpose of which is discussed in the following section relating to proton pumping as a possible mechanism).

Count bubbles of oxygen gas given off by elodea to determine the rate of photosynthesis.4.

Van Neil's proposal was confirmed 20 years later by using the O18 isotope of oxygen as a tracer label to follow the fate of oxygen atoms during photosynthesis.


Chlorophyll is the main photosynthetic pigment.

Photosynthesis involves the conversion of light energy into chemical energy.

Plants are the dominant photosynthetic autotrophs on the Earth.

any organisms in a reef aquarium rely on photosynthesis to survive. These include diatoms, green hair algae, cyanobacteria, macroalgae, clams and most corals and anemones that aquarists maintain. In the case of clams, corals and anemones, this photosynthesis is actually carried out by symbiotic organisms (zooxanthallae) that live within the tissue of the host animal. In every case, however, the cells that photosynthesize need to incorporate carbon dioxide somehow, and they excrete oxygen.

The Effect of PH on the Rate of Photosynthesis | Sciencing

Sometimes obtaining adequate carbon dioxide is easy for photosynthesizing organisms, and sometimes it is difficult, requiring them to develop special mechanisms to obtain it rapidly enough. In order to understand how this happens in a reef aquarium, it is first necessary to understand what happens to carbon dioxide when it dissolves into seawater.

arbon dioxide is an interesting molecule. When it dissolves into water it can take a number of different forms. Even the rate at which it can move between some of these forms impacts how organisms must develop special mechanisms to be able to take up enough during rapid photosynthesis.

Photosynthesis can be measured in many ways as it involves the production of oxygen, the uptake of carbon dioxide and an increase in biomass. For example, aquatic plants release oxygen bubbles during photosynthesis and so these can be collected and measured. The uptake of carbon dioxide is more difficult to measure so it is usually done indirectly. When carbon dioxide is absorbed from water the pH of the water rises and so this can be measured with pH indicators or pH meters. Finally, photosynthesis can be measured through an increase in biomass. If batches of plants are harvested at a series of times and the biomass of these batches is calculated, the rate increase in biomass gives an indirect measure of the rate of photosynthesis in the plants.
