Answer

Answer:

  1. d. Secondary structure
  2. d. Charge
  3. b. Sum the enthalpy changes of the known reactions

Brief Explanations:

  1. Alpha - helices and beta - pleated sheets are secondary protein structures formed by hydrogen - bonding within the polypeptide backbone.
  2. In half - reaction method for redox reactions, besides atoms, charge must be balanced in each half - reaction to account for electron transfer.
  3. Hess's Law is used to find the enthalpy change of a reaction by summing the enthalpy changes of a series of known reactions that add up to the target reaction.
