Final answer:
In deoxyHB, the atoms V98 and Y145 are held together by a covalent bond, Y145 and H146 by a hydrogen bond, and H146 and K40 by an ionic bond.
Step-by-step explanation:
The type of bonds that hold the atoms V98 and Y145, Y145 and H146, H146 and K40 in deoxyHB are, respectively, covalent bond, hydrogen bond, and ionic bond. Covalent bonds form when two atoms share electrons, creating a strong link between them. Hydrogen bonds, unlike covalent bonds, are weaker and occur when a hydrogen atom in one molecule is attracted to an electronegative atom, often oxygen or nitrogen, in another molecule. Any potential ionic bond between H146 and K40 happens because one atom gives up one or more electrons to another atom.
