A few cards from the deck
Glycolysis: what is it?
Show the answer
Breakdown of glucose into pyruvate in the cytoplasm, netting 2 ATP per glucose.
3 ATP when starting from glycogen.
Why does blood lactate rise sharply beyond a certain intensity?
- Production exceeds clearance
- The muscle suddenly lacks glucose
- The liver stops
- Type I fibres shut down
Show the answer
Production exceeds clearance
As long as clearance keeps up, blood lactate stays stable.
Lactate: what is it?
Show the answer
Made from pyruvate when it is not oxidised fast enough.
It is not waste: it is reused as fuel.
