Krebs cycle

The researchers found the neurons had a disrupted Krebs cycle -- the cellular process in mitochondria that produces most of the body's crucial molecular power source, ATP.

“Asking students questions like, ‘Tell me in three sentences what is the Krebs cycle in chemistry?’

The acetate, it turns out, was processed through a metabolic cycle known as the Krebs cycle.

The application includes nearly 200 templates for everything from blood vessels to the Krebs cycle.

Rerun the tape of evolution, and DNA, RNA, ATP, the Krebs cycle — the rigmarole of Biology 101 — would probably arise again, here or in distant worlds.
