About
This quiz focuses on the four major biomolecules—carbohydrates, lipids, proteins, and nucleic acids—and represents fundamental content for 9th grade biology students. The questions assess students' understanding of the structure, function, and elemental composition of each biomolecule class, requiring them to connect specific examples like enzymes and DNA to their broader molecular categories. Students need to distinguish between the energy storage functions of carbohydrates versus lipids, recognize that proteins are built from amino acids and serve structural roles like muscle formation, and understand that nucleic acids store genetic information through nucleotide sequences. The quiz also tests knowledge of elemental composition, particularly which elements are universal to all biomolecules versus those specific to certain classes, and requires students to identify functional roles such as enzymes belonging to proteins and cell membranes being primarily composed of lipids. Created by Christian Agudelo, a Biology teacher in Colombia who teaches grades 9-12. This quiz serves as an excellent formative assessment tool for introducing or reviewing the foundational concepts of biological macromolecules that students encounter early in their biology coursework. Teachers can utilize this quiz as a warm-up activity to gauge prior knowledge before diving deeper into molecular structure, as homework to reinforce classroom learning, or as review material before unit assessments. The question format works particularly well for identifying common misconceptions about biomolecule functions and helping students build the conceptual framework they need for more advanced topics like metabolism, cellular respiration, and protein synthesis. This assessment aligns with NGSS standards HS-LS1-6, which focuses on how molecular interactions within cells support life processes, and supports the development of scientific literacy skills outlined in biology curriculum standards nationwide.
