Understand the diverse roles of proteins in biological systems. Proteins are macromolecules that perform a wide range of functions essential for life.
Recognize that proteins are not primarily used for energy storage; this function is typically associated with carbohydrates and lipids.
Identify that storing genetic information is the role of nucleic acids, such as DNA and RNA, not proteins.
Learn that transporting oxygen in the blood is a specific function of the protein hemoglobin, which binds oxygen in red blood cells.
Understand that catalyzing biochemical reactions is a key function of enzymes, which are proteins that speed up chemical reactions in the body without being consumed in the process.
