  1. Which of the following statements is FALSE regarding the interaction of oxygen with myoglobin?

Oxygen is a homoallosteric effector of myoglobin.

  1. Which of the following occurs in hemoglobin when blood pH is lowered?

Histidine side chains at the subunit interface are charged at lower pH, forming salt bridges that stabilize the T state.

  1. The binding of one O2 to a molecule of hemoglobin results in:

An increased affinity for O2 in the remaining subunits (which have not yet bound O2)

  1. An increased affinity for O2 in the remaining subunits (which have not yet bound O2)

It covalently bonds heme into the hemoglobin subunit.

  1. Which of the following statements about the T and R states of hemoglobin is FALSE?

The T state is less stable than the R state at lower pH

  1. Which of the following statements is FALSE?

As pH decreases, the O2 binding curve of hemoglobin shifts to the right, because a greater proportion of hemoglobin molecules exist in the T-state at a given pO2.

  1. Which term best describes the histidine F8 residue in myoglobin and hemoglobin?

invariant residue

  1. Which of the following statements about the structure of myoglobin is TRUE?

A heme prosthetic group is tightly bound to myoglobin via a coordination bond.

  1. hich of the following statements is FALSE regarding the interaction of oxygen with myoglobin?

Oxygen is a homoallosteric effector of myoglobin.

  1. Which of the following statements about the T and R states of hemoglobin is FALSE?

The T state is less stable than the R state at lower pH.
