Hemoglobin binds bisphosphoglycerate (bpg) and oxygen at different locations. the protein itself changes conformation upon binding of bpg. allosteric modifiers, like bpg, can change the shape (conformation) and usually the activity of a protein upon binding. a) at increased levels of bpg, which direction would you expect the binding curves of oxygen to shift? b) how does bpg affect the total amount of o2 that can bind? c) how does bpg affect the affinity of o2 binding to hemoglobin? d) does bpg increase or decrease the kd of oxygen binding? e) would you expect the bpg levels of someone living at high altitudes to be higher or lower?

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
