Verified step by step guidance

Understand the role of proteins in the body: Proteins are macromolecules made up of amino acids and serve various functions, including structural support, transport, signaling, and catalysis of biochemical reactions.

Recognize that proteins do not store genetic information: Genetic information is stored in nucleic acids, such as DNA and RNA, not proteins.

Identify that proteins are not the primary energy source for cells: Carbohydrates and lipids are the main energy sources for cells, while proteins are primarily used for structural and functional roles.

Understand the role of enzymes: Enzymes are specialized proteins that catalyze biochemical reactions by lowering the activation energy required for reactions to occur, making them faster and more efficient.

Clarify that proteins do not form the phospholipid bilayer: The phospholipid bilayer of cell membranes is primarily composed of lipids, specifically phospholipids, with proteins embedded within or associated with the bilayer for functional purposes.
