2. How do you know if a certain acid is strong?
- It partially dissociates and has a Ka greater than 1
- It completely dissociates and has a Ka greater than 1
- It completely dissociates and has a Ka of less than 1
- It partially dissociates and has a Ka of less than 1
3. What is the Levinthal paradox (1968)?
- Protein folding must be predetermined as it would take a lot of time if the chain was randomly searched for the correct conformation
- Protein folding is random and the chain is randomly searched for the correct conformation
- Multiple conformations are attempted by proteins before the correct one is discovered
- None of the above
4. What can protein-folding be?
- Both
- None of the above
- Spontaneous
- Assisted
5. What is the Henderson-Hasselbach equation?
- log([A-]/[HA]) = pKa + pH
- pH = pKa - log([A-]/[HA])
- pH = pKa + log([A-]/[HA])
- pKa = pH + log([A-]/[HA])
