Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste products. Box 1. Plant carbon metabolism: photosynthesis, photorespiration and respiration For the purpose of this review, we focus on three metabolic processes that dominate carbon fluxes in vegetation: photosynthesis, photorespiration and respiration (Box Fig. 1 below). 1. How the Plants Obtain Carbon Dioxide: There are a large number of tiny pores called stomata on the surface of the leaves of plants (The singular of stomata is stoma). The green plants take carbon dioxide from air for photosynthesis. The carbon dioxide gas enters the leaves of the plant through the stomata present on their surface.

Photosynthesis is the biochemical pathway which converts the energy of light into the bonds of glucose molecules. The process of photosynthesis occurs in two steps.

  20. The effect of carbon dioxide concentration. The carbon dioxide concentration in the atmosphere is very low at around 0.04%. This means that low carbon dioxide concentrations often limit the rate of photosynthesis under normal conditions. Greenhouse growers often enrich the atmosphere with carbon dioxide to enable faster growth of crop plants.
  21. Carbon dioxide is present in the air we breathe at very low concentrations. Even though it forms about .04% of the air, it is a needed factor in light-independent photosynthesis. In higher concentrations, more carbon is incorporated into carbohydrates, therefore increasing the rate of photosynthesis in light-independent reactions.
