If [L] = 5 mM, [P] = 3 mM,
and [PL] = 2 mM, what is
the dissociation constant?
Which of the TWO Only crystallized proteins can be analyzed.

of a structural change that
does NOT play a role in
translating local binding of
oxygen to global protein
conformational change
would be the different
______ in the presence and
absence of oxygen

The figure below shows The lower pO2 in active muscle leads to release of O2
the oxygen binding curve from myoglobin.
for myoglobin in muscle.
Based on this curve, which
of the following is
correct?
