Condensation and Hydrolysis Reactions

Part A

Correct
Proteins are composed of amino acids joined together.
Part B

Correct
The central carbon atom in an amino acid is bonded to an amino functional group, a carboxyl functional group, a side chain, and hydrogen.
Part C

Correct
The carboxyl group (COOH) contains two oxygen atoms that tend to pull electrons away from the hydrogen atom, so this group tends to lose a proton and is acidic.
Part D

Correct
Nucleotide monomers make up nucleic acids.
Part E

Correct
A hydroxyl group is removed from the carboxyl group of one amino acid and hydrogen is removed from the amino group of the other amino acid, allowing a bond to form between the two groups.
Part F

Correct
Enzymes in the digestive tract break down food molecules, which is a process that occurs by hydrolysis.
