About This Assessment
AP Bio Functional Groups Quiz - Symptoms and Signs
Test how well you can recognize the functional groups emphasized in AP Biology and predict how they shape molecular properties and reactions. Across 16 questions, you’ll work with hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl groups in examples involving amino acids, ATP, proteins, phospholipids, and carbohydrates. You’ll receive one overall knowledge score with clear performance bands. Free to take, with no sign-up needed.
