One of the most challenging and confusing aspects of cellular/molecular biology is understanding how the electron transport chain (ETC) is utilized in cells to create energy. In this game-based activity, students will physically interact with different components of the thylakoid ETC as water is converted to oxygen and stored energy during the light-dependent reactions of photosynthesis. By playing a series of cards that represent different steps, students move electron pieces along a series of graphical representations of photosystems, cytochrome b6/f, and mobile elements to eventually deliver them to NADP+, while also creating a proton gradient that powers the ATP synthase. Additional attack cards also inform on the ways certain mutations and herbicides can impact functions required by the ETC. The level of detail modeled in this game best corresponds to a 2000/3000-level cell biology course but could be adapted as needed.
