Biochemistry
Glycolysis, Animated
An animated glycolysis pathway — glucose to pyruvate, PFK-1 as the rate-limiting step, and the net yield of 2 ATP and 2 NADH.
Follow the flux from glucose down to pyruvate. The committed, rate-limiting step (PFK-1) is flagged, and the ATP investment and payoff are tallied at the bottom.
- The full pathway, glucose → 2 pyruvate
- PFK-1 as the rate-limiting, committed step
- Where ATP is spent and made — net +2 ATP, +2 NADH
This is one of many living diagrams inside the Redox QBank, connected to notes and practice questions so it sticks.
