Skeletal muscles are made of long, thin cells that are packed with highly organized proteins and organelles. During strenuous exercise, the rate of energy use in skeletal muscles can increase by more ...

Many of us remember from high school biology class that mitochondria are the cell’s “power plants.” These small kidney-bean-shaped structures are what convert nutrients from food into ATP — the cell’s ...

Mitochondria are responsible for producing and providing energy to our bodies, especially in organs such as the heart, brain, and muscles, which require high-energy production. These organs ...

Scientists have long understood that parts of cells, called organelles, evolved to have certain shapes and sizes because their forms are closely related to how they function. Now, Johns Hopkins ...

Using new super-resolution microscopes, researchers at the University of California, Irvine and the University of Pennsylvania have for the first time observed electrical charge and discharge ...

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 ...

In a recent study published in Nature, researchers from the United States of America investigated how cells separate competing metabolic pathways within mitochondria, namely oxidative phosphorylation ...

Researchers at the University of Helsinki uncovered the mechanisms for a novel cellular stress response arising from the toxicity of newly synthesized proteins. Activation of the stress response is at ...

Mitochondria are the main producers of energy in cells, and lysosomes recycle cellular debris that accumulates during normal function of our cells. Neurons are highly dependent on energy production by ...
