2. You have traveled to the Amazon to discover new animals. You discover an animal that has only been described in folklore because it is very elusive (this new animal can remain under water without breathing for several hours). They can do this because they utilize nearly 100% of the oxygen in their blood (whereas we only use ~65% of ours). Because of your biochemistry training, you know to assess the oxygen binding protein, Hb, of these animals. You find that although 2,3-BPG does not bind Hb, bicarbonate ions do (in fact, these are strong negative allosteric effectors). In 3-4 sentences, please explain how this animal can remain under water without breathing for several hours and why this animal may have Hb that is responsive to bicarbonate ions instead of 2,3BPG
