Sentences with phrase «concentrate bicarbonate ions»

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.

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.

Instead, as with photosynthesis, calcifiers actively uptake the more abundant bicarbonate ions and concentrate them in compartments.

The majority of marine algae have carbon concentrating mechanisms (CCMs) that facilitate the active influx of CO2 and / or bicarbonate ions -LRB--RRB- and elevate C concentrations at the site of C fixation (i.e. Rubisco), with few algae being CO2 - only users [22,23].
