Pay-off phase ~Sara Petra
The pay of phase happens when energy is released in the form of 4 ATPs 2 per glyceraldehyde. During this phase One NADPH molecule is also produced. The last molecule is pyruvic acid(a three carbon sugar). Each step occurs twice per molecule of glucose.
At the end of the cycle if oxygen is present it will move on to The Krebs cycle through the link reaction, and if oxygen is not present it will not move past the link reaction.
At the end of the cycle it ends up with:
•2 ATPs
•2 NADPH
•2 Pyruvic acid
