Verified step by step guidance

Begin by understanding the basic structure and function of proteins in the body. Proteins are large, complex molecules that play many critical roles in the body, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules.

Recognize that proteins are composed of amino acids. Amino acids are organic compounds that combine to form proteins. They are linked together by peptide bonds, which are covalent chemical bonds formed between two amino acid molecules.

Clarify the synthesis location of proteins. Proteins are synthesized in the ribosomes of the cell, not the mitochondria. Ribosomes are the cellular structures responsible for protein synthesis, translating genetic information from mRNA to build proteins.

Understand the role of proteins in genetic information. Proteins are not the main source of genetic information; DNA is. DNA contains the instructions needed for an organism to develop, survive, and reproduce, while proteins execute these instructions.

Identify the storage function of proteins. Proteins are not primarily stored as a long-term energy reserve. Instead, fats and carbohydrates serve as the main energy reserves in the body. Proteins are primarily functional molecules rather than storage molecules.
