Question
- A. It requires heat to occur.
- B. It is a condensation reaction.
- C. It involves the addition of water.
- D. It produces energy.
Answer
It involves the addition of water.
Explanation
Hydrolysis involves the addition of water to proteins, which leads to the breakdown of peptide bonds and the formation of 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.
