Sentences with phrase «converts bicarbonate ion»

These microorganisms contain microcompartments named carboxysomes that encapsulate Rubisco in a protein shell and contain an enzyme, carbonic anhydrase (CA), which converts bicarbonate ion to CO2.

Not exact matches

With a higher internal pH, bicarbonate sheds an H + and converts into carbonate ions and when concentrated in the presence of concentrated Ca + +, calcium carbonate minerals readily form.

To overcome the limiting supply of CO2, organisms like coral concentrate bicarbonate ions in compartments into which they pump H + ions and lower the pH. As seen in Figure 2, at pH 5 or lower, 90 % of the DIC converts to CO2.

However below pH 7.0, nearly all carbonate ions (CO3 - 2) will be converted to bicarbonate (HCO3 --RRB-, so that carbonate ions no longer serve as buffering agents.

The reason for this is that bicarbonate is converted to carbonate in a warmer ocean, releasing a hydrogen ion thus stabilizing the pH.

This is a normal process, and over millions of years the oceans have remained slightly alkaline, as more acidic surface water mixes with deeper water, and carbonic acid is converted to bicarbonate ions.
