Which of the following is a common function of protein macromolecules in cells?
A
Catalyzing biochemical reactions as enzymes
B
Serving as the main long-term energy storage molecule in animals
C
Forming the hydrophobic core of biological membranes as the primary structural component
D
Storing genetic information as the primary hereditary material
Verified step by step guidance1
Understand the roles of different macromolecules in cells: proteins, lipids, carbohydrates, and nucleic acids each have distinct primary functions.
Recall that proteins often function as enzymes, which catalyze biochemical reactions, speeding up metabolic processes essential for life.
Recognize that long-term energy storage in animals is primarily the role of lipids (like fats), not proteins.
Know that the hydrophobic core of biological membranes is mainly formed by lipid molecules, specifically phospholipids, rather than proteins.
Remember that storing genetic information is the primary function of nucleic acids (DNA and RNA), not proteins.
