Cellular Respiration: Mitochondrial Electron Transport Chain
This model simulates the processes of proton transport and ATP formation in a mitochondrion. Students may observe the processes and explore the impacts of ETC inhibitors, ATP synthase inhibitors, uncoupling proteins, or absence of oxygen on these processes. This model is modified from a NetLogo simulation developed by Steven Brewer (2004). Detailed membrane structures, rules of proton movement and regulation, and oxygen impacts are constructed in this model to provide a powerful dynamic visualization to support NGSS-aligned active learning.
Blood Sugar Regulation by the Liver and Muscle
This model compares the processes of glucose regulation by the liver and muscle. Students may examine the two processes separately or in one system. Students may also observe the changes in blood sugar level regulated by glucose transportation, glycogenesis, and glycogenolysis.
