Verified step by step guidance

Begin by identifying the primary functions of proteins in biological systems. Proteins are versatile molecules that play crucial roles in various cellular processes.

Understand that proteins can act as enzymes, which are catalysts that speed up biochemical reactions without being consumed in the process. This is a fundamental function of proteins.

Recognize that proteins also provide structural support. For example, collagen is a protein that helps maintain the structural integrity of tissues.

Consider the role of proteins in transporting molecules across cell membranes. Proteins such as transporters and channels facilitate the movement of substances in and out of cells.

Finally, clarify that storing genetic information is not a function of proteins. This role is primarily carried out by nucleic acids, such as DNA and RNA, which are responsible for storing and transmitting genetic information.
