Cells are full of little machines that perform critical functions, like mitochondria, which are known as the powerhouses of the cell. But new research has revealed that in photoreceptor cells, ...

Mitochondria, the “powerhouses of the cell,” are vital cellular organelles that govern energy metabolism, maintain redox ...

Long before the earliest animals swam through the water-covered surface of Earth’s ancient past, one of the most important encounters in the history of life took place. A primitive bacterium was ...

A study on ground squirrels shows, not only do mitochondria produce bioenergy in the cone-shaped photoreceptors in the retina of the eye, they also act as micro-lenses that redirect light to the ...

Many of us remember from high school biology class that mitochondria are the cell's "power plants." These small ...

Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, Salk researchers have discovered a new function of mitochondria: they set off molecular ...

Like cells themselves, mitochondria have a membrane that filters materials entering and exiting their structure. That membrane relies on a difference in polarity known as “membrane potential” and when ...
