Question

This table summarizes the four main types of biomolecules found in living organisms. Each biomolecule has a specific structure and function that plays a critical role in biological processes. Understanding these biomolecules is fundamental in the study of biology and life sciences. BIOMOLECULE MONOMER POLYMER FUNCTION CARBOHYDRATES Monosaccharides Polysaccharides Provide energy & structural support PROTEINS Amino Acids Polypeptides Build/repair tissues, catalyze reactions LIPIDS Fatty Acids Triglycerides, Phospholipids Store energy long-term, form cell membranes, signaling NUCLEIC ACIDS Nucleotides DNA, RNA Store/transmit genetic info Which of the following is NOT a function of proteins? (1 point) Enzymatic catalysis Building structural support Cell signaling Repair damage

Answer 1

The function that is NOT typically associated with proteins from the options given is **cell signaling**. While proteins can be involved in signaling pathways and some proteins act as signaling molecules, the primary roles for proteins as highlighted in the table include building/repairing tissues and catalyzing reactions (enzymatic catalysis). Cell signaling is often more directly associated with lipids (e.g., steroid hormones) and certain carbohydrates (like glycoproteins).
