In plants, carbonic anhydrase helps raise the concentration of CO 2 within the chloroplast in order to increase the carboxylation rate of the enzyme RuBisCO. This is the reaction that integrates CO 2 into organic carbon sugars during photosynthesis , and can use only the CO 2 form of carbon, not carbonic acid or bicarbonate.
In plants, algae, and cyanobacteria, photosynthesis releases oxygen. This oxygenic photosynthesis is by far the most common type of photosynthesis used by living organisms. Some shade-loving plants (sciophytes) produce such low levels of oxygen during photosynthesis that they use all of it themselves instead of releasing it to the atmosphere. [12]
Carbonic anhydrase needs a family of carbon base enzymes for the hydration of carbon dioxide and acid–base homeostasis, that regulates PH levels in life. [32] [33] In plant life, liquid water is needed for photosynthesis, the biological process plants use to convert light energy and carbon dioxide into chemical energy. [34]
Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid.
Plants and yeast have anion transporters that in both the pericycle cells of plants and the plasma membrane of yeast cells export borate or boric acid (pKa = 9.2). [5] In A. thaliana , boron is exported from pericycle cells into the root stellar apoplasm against a concentration gradient for uptake into the shoots.
Carbonic anhydrase, an enzyme that requires zinc (gray sphere in this image), is essential for plant health. [1] Zinc deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium. Zinc is one of the most important micronutrients. [2]

The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
