1. Chapter 8 Which of the following statements describes from www.coursehero.com
A) binding of an atp molecule along with another substrate in an active site b) binding of a molecule to one subunit of a tetramer, which promotes faster binding to each of the other three subunits This phenomenon is called cooperativity. Example of homotropic regulation is binding of oxygen to haemoglobin.
1. Chapter 8 Which of the following statements describes
Found in the red blood cells of all animal life, hemoglobin is a gas transport and exchange protein that. The binding of a single ligand to the one of the protein subunit induces a conformational change to the rest of the subunits which increases the affinity of the ligand to other sub units. In general, cooperativity shows sigmoidal curves for all types of plots. One oxygen molecule can bind to the ferrous iron of a heme molecule in each of the four chains of a hemoglobin molecule.
