Final answer:
Proteins are the molecules that perform most of the chemical reactions in a cell. Proteins perform most chemical reactions in a cell by acting as enzymes. DNA and RNA are crucial for storing and translating genetic instructions for protein synthesis, but it is the proteins that function as the cell's main biochemical operatives.
Step-by-step explanation:
The chemical reactions in a cell are primarily performed by proteins. Proteins are involved in various cellular activities and perform virtually every function of a cell. They are composed of amino acids, which are the building blocks of proteins.

Most of the chemical reactions in a cell are performed by proteins. Proteins act as enzymes that catalyze biochemical reactions, which are critical for metabolism, signal transduction, and cell structure. DNA and RNA are involved in the genetic coding and regulation activities, where DNA contains the genetic blueprint and RNA plays a major role in the synthesis of proteins. However, proteins are the actual molecules that carry out most reactions by transforming substrates into products, facilitating the cell's various functional processes.
Nucleic acids, like DNA and RNA, provide the instructions needed for protein synthesis. During this process, mRNA is transcribed from DNA and then translated into polypeptides, which are long chains of amino acids linked by peptide bonds. These polypeptides fold into specific three-dimensional structures, resulting in functional proteins that perform virtually every function within the cell.
