About this resource

This quiz comprehensively covers fundamental biochemistry concepts appropriate for 9th-12th grade high school biology students, specifically those preparing for the New York State Living Environment Regents examination. The questions assess students' understanding of organic and inorganic molecules, enzyme structure and function, cellular organization, and basic cellular processes. Students need mastery of the four major biomolecules—carbohydrates, proteins, lipids, and nucleic acids—including their monomers, functions, and synthesis through dehydration reactions. They must understand enzyme specificity, how environmental factors like pH and temperature affect enzyme shape and function, and the relationship between protein structure and function. Additional concepts include levels of biological organization from organelles to organ systems, cellular structures and their roles, diffusion principles, and fundamental processes like photosynthesis and cellular respiration. Created by Charles Martinez, a Biology teacher in India who teaches grades 9-12. This comprehensive review quiz serves multiple instructional purposes, functioning effectively as a cumulative assessment tool before the Regents exam, a diagnostic instrument to identify knowledge gaps, or structured practice for reinforcing biochemistry fundamentals throughout the academic year. Teachers can deploy this quiz as a warm-up activity by selecting specific question clusters, assign it as homework for independent review, or use it for formative assessment to guide instruction. The quiz aligns with New York State Learning Standards for Living Environment, specifically supporting Performance Indicator 1.1 (living things are composed of cells), Performance Indicator 1.2 (cells carry on life functions), and Performance Indicator 5.1 (organic compounds can be synthesized by living organisms). The diverse question formats and comprehensive content coverage make this an invaluable resource for reinforcing student understanding of biochemical principles essential for success on the Living Environment Regents examination.
