Question
The binding of this metal and oxygen in myoglobin is tight and non-cooperative, closely following the Michaelis–Menten equation. For 10 points each:
[10e] Name this metal that gives hemoglobin its red color. This metal’s deficiency causes anemia.
ANSWER: iron [or Fe]
[10h] This quantity that measures binding cooperativity is 1 for myoglobin but 2.8 for hemoglobin. This number exponentiates the concentration terms in a modified form of the Michaelis–Menten equation.
ANSWER: Hill coefficient [prompt on n; prompt on Hill equation or Hill–Langmuir equation]
[10m] Myoglobin binds to oxygen about as tightly as hemoglobin binds to this other gas. Since this gas binds 200 times tighter to hemoglobin than oxygen does, it causes hypoxia with almost no symptoms.
ANSWER: carbon monoxide [or CO]
