Identify each protein structure level described below. a. may involve hydrogen bonds, salt bridges, and disulfide bonds that determine a protein’s three- dimensional structure
b. is determined by the interaction of several polypeptides coming together
c. is the amino acid sequence of a protein

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
