Metallothioneins are a class of compounds that are cysteine-rich
and low molecular weight proteins which bind to heavy metals. It is
suggested that cadmium (Cd) concentrations in oysters bioaccumulate
because Cd binds to metallothioneins present in the gills of the
oysters (Lekhi et al., 2008). The amino acid cysteine has the
following chemical structure:
a. Circle all the possible ligand atoms (donor atoms) in
cysteine.
b. Of the ligand atoms you circled, identify whether they are
A-type or B-type.

Which assumption is not part of the kinetic-molecular theory of gases? A. The kinetic energy of gas particles change with change in temperature. B. Because the space between gas particles is large, gas particles exert no attractive forces on each other. C. When gas particles collide with each other, they rebound and travel in new directions D. The size of gas particles is small compared to the space between the particles. E. Gas consists of particles that move randomly and...
