The Bohr effect refers to the decrease in affinity of Hb for 02 when the pH goes up. OA. the decrease in affinity of Hb for 02 when the pH goes down. O B. the increase in affinity of Hb for 02 when the 02 concentration goes up. OC. the decrease in affinity of Hb for 02 when the BPG concentration goes up. D. the decrease in affinity of Hb for 02 when the BPG concentration goes down E.

A scientist extracted compounds from apple peel and separated them using gel exclusion chromatography. Indicate which would be the expected order of elution from first eluted to last.

Buffer systems can absorb hydrogen ions from the blood to increase pH into homeostatic range (pH: 7.35 to 7.45)During what condition would buffer systems do this?
