This animation shows the reactions of the citric acid cycle, which splits off carbon atoms and generates energy-rich reduced forms of cofactor molecules. It is the first of three animations about cellular respiration.
This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.
The COVID-19 pandemic has spotlighted the importance of having a scientifically literate public. In this article, Pennsylvania educator Bob Cooper unpacks how to utilize BioInteractive's suite of infectious disease resources to teach students scientific literacy.
Across the U.S. and in Europe, researchers and health officials say they can track the course of a community outbreak of the new coronavirus by studying the waste flushed from its bathrooms. And that can provide a valuable addition to public health tools, they say.
In order to develop complex scientific explanations, students need to have many opportunities to grapple with a concept. In this Educator Voices article, hear how Amy Fassler uses a sequence of resources in a process called “curriculum spiraling.”
