Concept #1: Hemoglobin Displays Positive Cooperativity

Concept #2: Concerted & Sequential Models Explain Hb's Positive Cooperativity

Concept #3: Oxygen-Binding Curves

Concept #4: Positive Cooperativity makes Hb a Better O2 Transporter than Mb

Practice: In the binding of oxygen to myoglobin, the relationship between the concentration of oxygen and the fraction of binding sites occupied can best be described as:

Practice: Oxygen is a _____________ allosteric _____________ that promotes additional O2 binding to hemoglobin.

Practice: The binding of Oxygen to stabilize the R-state of Hemoglobin is best explained by which model(s)?
