Transporter mutation alters cell energy

The cotransporter NKCC1 moves sodium, potassium and chloride ions across the cell membrane and has roles regulating cell volume, epithelial transport and neuronal excitability.

How diversity of respiratory quinones affects microbial physiology

A new study provides a fundamental understanding of the diversification of small molecules called respiratory quinones and its adaptive consequences in bacterial species. Bioengineers at the University of California San Diego ...

Slowing down: Is aging caused by decreased cellular metabolism?

Throughout history, humans have been obsessed with finding a way to prevent aging and prolong life. Although the mechanisms have long eluded us, modern science is revealing more and more about the aging process. Now, researchers ...

Structure of a mitochondrial ATP synthase

ATP synthase is a universal molecular machine for energy conversion. By coupling to cellular respiration in mitochondria, it catalyzes conversion of chemical energy of cells.
