Glycolysis Demystified

By TNteam • Jan 4th, 2008 • Category: Biology

A simplified, yet useful version of [Figure 9.9 on page 166 of our textbook] GLYCOLYSIS:
 Energy Investment:
1]  Hexokinase phosphorylates glucose [using 1 ATP]
2] Phosphoglucoisomerase changes glucose-6-phosphate to fructose-6-phosphate [its isomer]
3] Phosphofructokinase phosphorylates fructose-6-phosphate [using 2nd ATP]
4] Aldolase splits into two isomers: dihydroxyacetone phosphate and glyceraldehyde-3-phosphate
5] Isomerase alternates between these two isomers [but more toward glyceraldehyde-3-phosphate
Energy Payoff
