This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the third 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.
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.
The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.
For the first time, scientists have shown that hummingbirds can sing and hear in pitches beyond the known range of other birds, according to research published Friday in the journal Science Advances.
Rutgers University researchers have received U.S. government clearance for the first saliva test to help diagnose COVID-19, a new approach that could help expand testing options and reduce risks of infection for health care workers.
Why aren’t health officials warning people about eating food contaminated with the new coronavirus? The answer has to do with the varying paths organisms take to make people sick.
This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.
Women who use certain types of hormones after menopause still have an increased risk of developing breast cancer nearly two decades after they stop taking the pills, long-term results from a big federal study suggest.
