What member of buffer system resists a drop in pH?
bicarbonate (base)
At what pH is a buffer effective?
buffers help resist change in pH. In our bodies the normal pH is 7.4 which is slightly basic. If for some reason there are excess hydrogen ions in our bodies, the pH will drop and a buffer in the body will counteract this. For example bicarbonate, an important buffer in our bodies, will release bicarbonate ions that will combine with the hydrogen ions forming carbonic acid. Therefore the blood will not decrease in pH.
Why are buffers needed in the blood?
because it is alkaline in nature
What is the principle buffer in the body?
A buffer is something that regulates or maintains the pH in the body. In the human body, carbonate is the main buffer in the blood and phosphate is the main buffer within cells.
What type of molecule prevents extensive changes in the pH of living organisms?
humans use bicarbonate as a PH buffer in the bloodBuffering of course!
What are the pH's of sodium carbonate and sodium bicarbonate?
Sodium carbonate has a pH of about 11, and sodium bicarbonate has a pH of 8.
What role does sodium bicarbonate in cell culture?
It works to maintain the pH of the media in an acceptable range by acting as a buffer. see related link

How do Carbonic acid and Bicarbonate works to maintain t pH blood?
This is a conjugate acid/base pair that works as a buffer to keep the blood within acceptable pH range H2CO3 <-> HCO3 -

What happens when carbonic acid sodium bicarbonate buffer pair buffer an acid?
the pH of the blood drops slightly

How does the Blood buffer system work?
Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3

Why use different buffers for a range of ph?
Each buffer will only be of sufficient capacity within a pH interval of pKa+1 > pH > pKa-1 so the optimal buffer pH-range is maximum 2 units.
