Question
- A. The formation of peptide bonds
- B. The addition of water to break peptide bonds
- C. The removal of water to form proteins
- D. The synthesis of amino acids
Answer
The addition of water to break peptide bonds
Explanation
During hydrolysis, water is added to break the peptide bonds in proteins, resulting in the formation of individual amino acids.
Common mistake
Confusion in Hydrolysis Process
Students often confuse hydrolysis of proteins with condensation reactions, thinking that hydrolysis involves forming bonds instead of breaking them.
Remember that hydrolysis is the process of breaking down proteins into amino acids by adding water. The formula for hydrolysis can be represented as: Protein + H2O → Amino Acids. In this reaction, water is used to break the peptide bonds. Therefore, the correct understanding is that hydrolysis involves the addition of water to break bonds, not the formation of new ones.
