Answer
In the denaturation of proteins, the bonds that typically break are the non-covalent interactions such as hydrogen bonds and ionic bonds. These interactions stabilize the protein's secondary and tertiary structures. However, covalent bonds, such as disulfide bridges, generally remain intact during denaturation.

Answer
During hydrolysis, the covalent bonds that link amino acids in the protein's primary structure are broken. This process involves the addition of water, leading to the conversion of the polypeptide into individual amino acids.
