How the Cereal Crumbles : A Hands-On Activity for Enzyme Kinetics and Thermodynamics in Introductory Biology (Journal Article) United States :National Association of Biology Teachers (NABT) ,2023 252–258p. American Biology Teacher Volume 85: Issue 5, May 2023 ***______{For Hard Copy, Please visit Library.}________*** Abstract: Concepts relating to enzymes and energy are central to understanding chemical and biological processes at the molecular level. Student learning of these crosscutting concepts can be challenging, so it is important to identify misconceptions and remediate them early, especially in introductory classes. Here we describe an activity in which undergraduate introductory biology students timed themselves crushing pieces of cereal to simulate and quantify the progress of an enzymatic reaction in the presence of competitive and noncompetitive inhibitors, and we asked students to connect the cereal analogy to concepts of thermodynamics. We developed an assessment and short surveys to evaluate the impact of the activity and to identify persistent misconceptions. Measurable improvements of assessment scores and qualitative student survey responses demonstrate the value of including a hands-on activity along with other modes of instruction. enzymes| enzyme kinetics| energy| active learning Nash, Troy R. | Pannell, Megan D. https://doi.org/10.1525/abt.2023.85.5.252 PER 0 0 0 0 RIEBPL RIEBPL 2024-04-09 0 2024-04-09 10:18:39 2024-04-09 PER 45670 45669
