Carbon dioxide in photosynthesis

The study supports a long-standing theory among scientists that higher concentrations of CO2 would allow vegetation to use water more efficiently, leading to increased levels of photosynthesis. Photosynthesis is the chemical process that plants use to create food for themselves.

carbon dioxide + water (+ light energy) → glucose + oxygen

The carbonates can redissolve releasing carbon dioxide back to the air or water.

That's whywe call it PHOTOsynthesis.

Under moderate temperature conditions when C3 plants have sufficient water, the supply of carbon dioxide is abundant and photorespiration is not a problem. The CO2 concentration of the atmosphere as of 2004 was about 380 ppm and this CO2 freely diffuses through the stomata of leaves and across the membranes of the while water diffuses out through the stomata. But during hot and dry conditions, the stomata close to prevent excessive water loss and the continuing fixation of carbon in the dramatically reduces the relative concentration of CO2. When it reaches a critical level of about 50 ppm the rubisco stops fixing CO2 and begins to fix O2 instead. Even though the detoured process feeds some PGA back into the cycle, the photorespiration process causes rubisco to operate at only about 25% of its optimal rate.

Here is the equation for photosynthesis:

Photosynthesis results in an increase in ; i.e. there is more carbohydrate in the plant. They can turn some of the glucose into fat or protein. They have to make lots of different chemicals to grow, but the two most important ones are fats and proteins. To do this they need energy (growth requires energy from glucose). Plants also have to make a very special chemical called DNA: this is the hereditary chemical of all animals and plants. They must also make lots of new chlorophyll.

Let's see how plants get the carbon dioxide and water they need for this process.

Which word equation summarizesphotosynthesis?

The carbon dioxide (CO2) then combines with water (H2O), and in the presence of sunlight then creates sugar (CH2O) and releases oxygen (O2) in the process as well.

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.)

Hence photosynthesis and respiration lie on complete opposite ends of the spectrum.

The chemical equation for photosynthesis is:

The study also helped explain a mystery about atmospheric carbon. Atmospheric carbon has two different forms, or isotopes, carbon-12 and carbon-13. Carbon-13 is less common, yet the researchers found that it is building up in the atmosphere more quickly than expected. They concluded that something must be removing extra carbon-12.

Depending on all these factors, the different kinds of photosynthesis can be classified as follows.

Light reaction and photophosphorylation
Pigments embedded on thylakoid membranes form photosystems. There are of two types: PS I P700, PS II P680. Components of photosystem I and II transfer the electrons from water to NADP via cyclic electron transfer or non-cyclic electron transfer. During electron transfer, the light energy captured by the photosynthetic organisms is transformed into the phosphate bond energy of ATP. This is called photophosphorylation. NADPH is generated during non-cyclic electron transfer.

In practice, any one of these factors could limit the rate of photosynthesis.

We consume oxygen from the atmosphere, which then reacts with the sugar in the body and creates energy by breaking up this sugar, and also release carbon dioxide and water in the process.
