Question

Both myoglobin and hemoglobin are conjugated proteins, they both contain heme which is a Term 1positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease . In terms of shape, the oxygen binding curve of myoglobin is  Term 2positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease and that of hemoglobin is Term 3positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease .  When one oxygen molecule is bound to hemoglobin, it becomes easier for the next to bind. This phenomena is called Term 4positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecreaseTerm 5positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease . In these proteins the Term 6positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecreaseTerm 7positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease is seen to coordinate with the heme iron.  Bound oxygen coordinates with the heme iron on the other side and the Term 8positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecreaseTerm 9positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease forms a hydrogen bond with the oxygen.  Hemoglobin can exist in two conformational states: one is the R state which would be  Term 10positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease Hb while the Term 11positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease state would be Term 12positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease Hb. The molecule Term 13positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease binds hemoglobin in its central cavity.  The effect of this molecule is to Term 14positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease hemoglobin's affinity for oxygen. Hemoglobin is also influenced by pH. This is called the Term 15positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease effect. A decrease in pH will Term 16positivenegativehistidineproximaldistalcooperativityprosthetic groupoxydeoxyTRBohrBPGhyperbolicsigmoidalchaperoneironmodified amino acidincreasedecrease hemoglobin's affinity for oxygen.
