Why might an oxygen dissociation curve be sigmoidal?

WebThis curve means that hemoglobin has a lower affinity for oxygen, binds oxygen relatively weakly and releases it more easily than myoglobin. When binding with oxygen what type of binding curve does hemoglobin have? In red blood cells, the oxygen-binding curve for hemoglobin displays an S shaped called a sigmoidal curve.

C) Hemoglobin exhibits cooperative binding of O2, while myoglobin does not. WebOct 3, 2016 · Myoglobin is a monomeric heme-containing, oxygen-carrying protein abundant in muscle. Its secondary structure consists of mostly α helix, and is devoid of β sheet. In the tertiary structure, the eight α helices pack together mainly in two layers, with adjacent helices mostly antiparallel and sometimes crossing at fairly sharp angles.
